Moves the 3Com drivers into drivers/net/ethernet/3com/ and the necessary
Kconfig and Makefile changes.

Did not move the following drivers becuase they use a non-3Com
chipset: 3c503, 3c505, 3c507, 3c523 and 3c527

-    the default address for cards when loaded as a module, but that's

-    Added traps for interrupts hitting the window as we clear and TX load
-    the board. Now getting 150K/second FTP with a 3c501 card. Still playing
-    with a TX-TX optimisation to see if we can touch 180-200K/second as seems

-/**
- * DOC: 3c501 Card Notes
- *
- *  Some notes on this thing if you have to hack it.  [Alan]
- *
- *  Some documentation is available from 3Com. Due to the boards age
- *  standard responses when you ask for this will range from 'be serious'
- *  to 'give it to a museum'. The documentation is incomplete and mostly
- *  of historical interest anyway.
- *
- *  The basic system is a single buffer which can be used to receive or
- *  transmit a packet. A third command mode exists when you are setting
- *  things up.
- *
- *  If it's transmitting it's not receiving and vice versa. In fact the
- *  time to get the board back into useful state after an operation is
- *  quite large.
- *
- *  The driver works by keeping the board in receive mode waiting for a
- *  packet to arrive. When one arrives it is copied out of the buffer
- *  and delivered to the kernel. The card is reloaded and off we go.
- *
- *  When transmitting lp->txing is set and the card is reset (from
- *  receive mode) [possibly losing a packet just received] to command
- *  mode. A packet is loaded and transmit mode triggered. The interrupt
- *  handler runs different code for transmit interrupts and can handle
- *  returning to receive mode or retransmissions (yes you have to help
- *  out with those too).
- *
- * DOC: Problems
- *
- *  There are a wide variety of undocumented error returns from the card
- *  and you basically have to kick the board and pray if they turn up. Most
- *  only occur under extreme load or if you do something the board doesn't
- *  like (eg touching a register at the wrong time).
- *
- *  The driver is less efficient than it could be. It switches through
- *  receive mode even if more transmits are queued. If this worries you buy
- *  a real Ethernet card.
- *
- *  The combination of slow receive restart and no real multicast
- *  filter makes the board unusable with a kernel compiled for IP
- *  multicasting in a real multicast environment. That's down to the board,
- *  but even with no multicast programs running a multicast IP kernel is
- *  in group 224.0.0.1 and you will therefore be listening to all multicasts.
- *  One nv conference running over that Ethernet and you can give up.

-
-       Known limitations:
-       Because of the way 3c509 ISA detection works it's difficult to predict
-       a priori which of several ISA-mode cards will be detected first.
-
-       This driver does not use predictive interrupt mode, resulting in higher
-       packet latency but lower overhead.  If interrupts are disabled for an
-       unusually long time it could also result in missed packets, but in
-       practice this rarely happens.
-
-
-       FIXES:
-               Alan Cox:       Removed the 'Unexpected interrupt' bug.
-               Michael Meskes: Upgraded to Donald Becker's version 1.07.
-               Alan Cox:       Increased the eeprom delay. Regardless of
-                               what the docs say some people definitely
-                               get problems with lower (but in card spec)
-                               delays
-               v1.10 4/21/97 Fixed module code so that multiple cards may be detected,
-                               other cleanups.  -djb
-               Andrea Arcangeli:       Upgraded to Donald Becker's version 1.12.
-               Rick Payne:     Fixed SMP race condition
-               v1.13 9/8/97 Made 'max_interrupt_work' an insmod-settable variable -djb
-               v1.14 10/15/97 Avoided waiting..discard message for fast machines -djb
-               v1.15 1/31/98 Faster recovery for Tx errors. -djb
-               v1.16 2/3/98 Different ID port handling to avoid sound cards. -djb
-               v1.18 12Mar2001 Andrew Morton
-                       - Avoid bogus detect of 3c590's (Andrzej Krzysztofowicz)
-                       - Reviewed against 1.18 from scyld.com

-               v1.19  16Oct2002 Zwane Mwaikambo <zwane@linuxpower.ca>
-                       - Additional ethtool features
-               v1.19a 28Oct2002 Davud Ruggiero <jdr@farfalle.com>
-                       - Increase *read_eeprom udelay to workaround oops with 2 cards.
-               v1.19b 08Nov2002 Marc Zyngier <maz@wild-wind.fr.eu.org>
-                       - Introduce driver model for EISA cards.
-               v1.20  04Feb2008 Ondrej Zary <linux@rainbow-software.org>

-                               Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com 3c515 ISA Fast EtherLink XL,
-3Com's ISA bus adapter for Fast Ethernet.  Due to the unique I/O port layout,
-it's not practical to integrate this driver with the other EtherLink drivers.
-
-II. Board-specific settings
-
-The Corkscrew has an EEPROM for configuration, but no special settings are
-needed for Linux.
-
-III. Driver operation
-
-The 3c515 series use an interface that's very similar to the 3c900 "Boomerang"
-PCI cards, with the bus master interface extensively modified to work with
-the ISA bus.
-
-The card is capable of full-bus-master transfers with separate
-lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
-DEC Tulip and Intel Speedo3.
-
-This driver uses a "RX_COPYBREAK" scheme rather than a fixed intermediate
-receive buffer.  This scheme allocates full-sized skbuffs as receive
-buffers.  The value RX_COPYBREAK is used as the copying breakpoint: it is
-chosen to trade-off the memory wasted by passing the full-sized skbuff to
-the queue layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control.  One
-is the send-packet routine, which enforces single-threaded use by the netif
-layer.  The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-IV. Notes
-
-Thanks to Terry Murphy of 3Com for providing documentation and a development
-board.
-
-The names "Vortex", "Boomerang" and "Corkscrew" are the internal 3Com
-project names.  I use these names to eliminate confusion -- 3Com product
-numbers and names are very similar and often confused.
-
-The new chips support both ethernet (1.5K) and FDDI (4.5K) frame sizes!
-This driver only supports ethernet frames because of the recent MTU limit
-of 1.5K, but the changes to support 4.5K are minimal.

-                               Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com FastEtherLink and FastEtherLink
-XL, 3Com's PCI to 10/100baseT adapters.  It also works with the 10Mbs
-versions of the FastEtherLink cards.  The supported product IDs are
-  3c590, 3c592, 3c595, 3c597, 3c900, 3c905
-
-The related ISA 3c515 is supported with a separate driver, 3c515.c, included
-with the kernel source or available from
-    cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board.  The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line.
-
-The EEPROM settings for media type and forced-full-duplex are observed.
-The EEPROM media type should be left at the default "autoselect" unless using
-10base2 or AUI connections which cannot be reliably detected.
-
-III. Driver operation
-
-The 3c59x series use an interface that's very similar to the previous 3c5x9
-series.  The primary interface is two programmed-I/O FIFOs, with an
-alternate single-contiguous-region bus-master transfer (see next).
-
-The 3c900 "Boomerang" series uses a full-bus-master interface with separate
-lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
-DEC Tulip and Intel Speedo3.  The first chip version retains a compatible
-programmed-I/O interface that has been removed in 'B' and subsequent board
-revisions.
-
-One extension that is advertised in a very large font is that the adapters
-are capable of being bus masters.  On the Vortex chip this capability was
-only for a single contiguous region making it far less useful than the full
-bus master capability.  There is a significant performance impact of taking
-an extra interrupt or polling for the completion of each transfer, as well
-as difficulty sharing the single transfer engine between the transmit and
-receive threads.  Using DMA transfers is a win only with large blocks or
-with the flawed versions of the Intel Orion motherboard PCI controller.
-
-The Boomerang chip's full-bus-master interface is useful, and has the
-currently-unused advantages over other similar chips that queued transmit
-packets may be reordered and receive buffer groups are associated with a
-single frame.
-
-With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
-Rather than a fixed intermediate receive buffer, this scheme allocates
-full-sized skbuffs as receive buffers.  The value RX_COPYBREAK is used as
-the copying breakpoint: it is chosen to trade-off the memory wasted by
-passing the full-sized skbuff to the queue layer for all frames vs. the
-copying cost of copying a frame to a correctly-sized skbuff.
-
-IIIC. Synchronization
-The driver runs as two independent, single-threaded flows of control.  One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag.  The other thread is the interrupt handler, which is single
-threaded by the hardware and other software.
-
-IV. Notes
-
-Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
-3c590, 3c595, and 3c900 boards.
-The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
-the EISA version is called "Demon".  According to Terry these names come
-from rides at the local amusement park.
-
-The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
-This driver only supports ethernet packets because of the skbuff allocation
-limit of 4K.

- * To enable jumbo frames, simply specify an mtu between 1500 and 9000
- * bytes to ifconfig. Jumbo frames can be enabled or disabled at any time
- * by running `ifconfig eth<X> mtu <MTU>' with <X> being the Ethernet
- * interface number and <MTU> being the MTU value.
- *
- * Module parameters:
- *
- * When compiled as a loadable module, the driver allows for a number
- * of module parameters to be specified. The driver supports the
- * following module parameters:
- *
- *  trace=<val> - Firmware trace level. This requires special traced
- *                firmware to replace the firmware supplied with
- *                the driver - for debugging purposes only.
- *
- *  link=<val>  - Link state. Normally you want to use the default link
- *                parameters set by the driver. This can be used to
- *                override these in case your switch doesn't negotiate
- *                the link properly. Valid values are:
- *         0x0001 - Force half duplex link.
- *         0x0002 - Do not negotiate line speed with the other end.
- *         0x0010 - 10Mbit/sec link.
- *         0x0020 - 100Mbit/sec link.
- *         0x0040 - 1000Mbit/sec link.
- *         0x0100 - Do not negotiate flow control.
- *         0x0200 - Enable RX flow control Y
- *         0x0400 - Enable TX flow control Y (Tigon II NICs only).
- *                Default value is 0x0270, ie. enable link+flow
- *                control negotiation. Negotiating the highest
- *                possible link speed with RX flow control enabled.
- *
- *                When disabling link speed negotiation, only one link
- *                speed is allowed to be specified!
- *
- *  tx_coal_tick=<val> - number of coalescing clock ticks (us) allowed
- *                to wait for more packets to arive before
- *                interrupting the host, from the time the first
- *                packet arrives.
- *
- *  rx_coal_tick=<val> - number of coalescing clock ticks (us) allowed
- *                to wait for more packets to arive in the transmit ring,
- *                before interrupting the host, after transmitting the
- *                first packet in the ring.
- *
- *  max_tx_desc=<val> - maximum number of transmit descriptors
- *                (packets) transmitted before interrupting the host.
- *
- *  max_rx_desc=<val> - maximum number of receive descriptors
- *                (packets) received before interrupting the host.
- *
- *  tx_ratio=<val> - 7 bit value (0 - 63) specifying the split in 64th
- *                increments of the NIC's on board memory to be used for
- *                transmit and receive buffers. For the 1MB NIC app. 800KB
- *                is available, on the 1/2MB NIC app. 300KB is available.
- *                68KB will always be available as a minimum for both
- *                directions. The default value is a 50/50 split.
- *  dis_pci_mem_inval=<val> - disable PCI memory write and invalidate
- *                operations, default (1) is to always disable this as
- *                that is what Alteon does on NT. I have not been able
- *                to measure any real performance differences with
- *                this on my systems. Set <val>=0 if you want to
- *                enable these operations.
- *
- * If you use more than one NIC, specify the parameters for the
- * individual NICs with a comma, ie. trace=0,0x00001fff,0 you want to
- * run tracing on NIC #2 but not on NIC #1 and #3.
- *
- * TODO:
- *
- * - Proper multicast support.
- * - NIC dump support.
- * - More tuning parameters.
- *
- * The mini ring is not used under Linux and I am not sure it makes sense
- * to actually use it.
- *
- * New interrupt handler strategy:
- *
- * The old interrupt handler worked using the traditional method of
- * replacing an skbuff with a new one when a packet arrives. However
- * the rx rings do not need to contain a static number of buffer
- * descriptors, thus it makes sense to move the memory allocation out
- * of the main interrupt handler and do it in a bottom half handler
- * and only allocate new buffers when the number of buffers in the
- * ring is below a certain threshold. In order to avoid starving the
- * NIC under heavy load it is however necessary to force allocation
- * when hitting a minimum threshold. The strategy for alloction is as
- * follows:
- *
- *     RX_LOW_BUF_THRES    - allocate buffers in the bottom half
- *     RX_PANIC_LOW_THRES  - we are very low on buffers, allocate
- *                           the buffers in the interrupt handler
- *     RX_RING_THRES       - maximum number of buffers in the rx ring
- *     RX_MINI_THRES       - maximum number of buffers in the mini ring
- *     RX_JUMBO_THRES      - maximum number of buffers in the jumbo ring
- *
- * One advantagous side effect of this allocation approach is that the
- * entire rx processing can be done without holding any spin lock
- * since the rx rings and registers are totally independent of the tx
- * ring and its registers.  This of course includes the kmalloc's of
- * new skb's. Thus start_xmit can run in parallel with rx processing
- * and the memory allocation on SMP systems.
- *
- * Note that running the skb reallocation in a bottom half opens up
- * another can of races which needs to be handled properly. In
- * particular it can happen that the interrupt handler tries to run
- * the reallocation while the bottom half is either running on another
- * CPU or was interrupted on the same CPU. To get around this the
- * driver uses bitops to prevent the reallocation routines from being
- * reentered.
- *
- * TX handling can also be done without holding any spin lock, wheee
- * this is fun! since tx_ret_csm is only written to by the interrupt
- * handler. The case to be aware of is when shutting down the device
- * and cleaning up where it is necessary to make sure that
- * start_xmit() is not running while this is happening. Well DaveM
- * informs me that this case is already protected against ... bye bye
- * Mr. Spin Lock, it was nice to know you.
- *
- * TX interrupts are now partly disabled so the NIC will only generate
- * TX interrupts for the number of coal ticks, not for the number of
- * TX packets in the queue. This should reduce the number of TX only,
- * ie. when no RX processing is done, interrupts seen.
- */

-/*
- * Threshold values for RX buffer allocation - the low water marks for

+
+    Fixed (again!) the missing interrupt locking on TX/RX shifting.
+       Alan Cox <alan@lxorguk.ukuu.org.uk>
+
+    Removed calls to init_etherdev since they are no longer needed, and
+    cleaned up modularization just a bit. The driver still allows only
+    the default address for cards when loaded as a module, but that's
+    really less braindead than anyone using a 3c501 board. :)
+                   19950208 (invid@msen.com)
+
+    Added traps for interrupts hitting the window as we clear and TX load
+    the board. Now getting 150K/second FTP with a 3c501 card. Still playing
+    with a TX-TX optimisation to see if we can touch 180-200K/second as seems
+    theoretically maximum.
+               19950402 Alan Cox <alan@lxorguk.ukuu.org.uk>
+
+    Cleaned up for 2.3.x because we broke SMP now.

+/**
+ * DOC: 3c501 Card Notes
+ *
+ *  Some notes on this thing if you have to hack it.  [Alan]
+ *
+ *  Some documentation is available from 3Com. Due to the boards age
+ *  standard responses when you ask for this will range from 'be serious'
+ *  to 'give it to a museum'. The documentation is incomplete and mostly
+ *  of historical interest anyway.
+ *
+ *  The basic system is a single buffer which can be used to receive or
+ *  transmit a packet. A third command mode exists when you are setting
+ *  things up.
+ *
+ *  If it's transmitting it's not receiving and vice versa. In fact the
+ *  time to get the board back into useful state after an operation is
+ *  quite large.
+ *
+ *  The driver works by keeping the board in receive mode waiting for a
+ *  packet to arrive. When one arrives it is copied out of the buffer
+ *  and delivered to the kernel. The card is reloaded and off we go.
+ *
+ *  When transmitting lp->txing is set and the card is reset (from
+ *  receive mode) [possibly losing a packet just received] to command
+ *  mode. A packet is loaded and transmit mode triggered. The interrupt
+ *  handler runs different code for transmit interrupts and can handle
+ *  returning to receive mode or retransmissions (yes you have to help
+ *  out with those too).
+ *
+ * DOC: Problems
+ *
+ *  There are a wide variety of undocumented error returns from the card
+ *  and you basically have to kick the board and pray if they turn up. Most
+ *  only occur under extreme load or if you do something the board doesn't
+ *  like (eg touching a register at the wrong time).

+
+       Known limitations:
+       Because of the way 3c509 ISA detection works it's difficult to predict
+       a priori which of several ISA-mode cards will be detected first.
+
+       This driver does not use predictive interrupt mode, resulting in higher
+       packet latency but lower overhead.  If interrupts are disabled for an
+       unusually long time it could also result in missed packets, but in
+       practice this rarely happens.
+
+
+       FIXES:
+               Alan Cox:       Removed the 'Unexpected interrupt' bug.
+               Michael Meskes: Upgraded to Donald Becker's version 1.07.
+               Alan Cox:       Increased the eeprom delay. Regardless of
+                               what the docs say some people definitely
+                               get problems with lower (but in card spec)
+                               delays
+               v1.10 4/21/97 Fixed module code so that multiple cards may be detected,
+                               other cleanups.  -djb
+               Andrea Arcangeli:       Upgraded to Donald Becker's version 1.12.
+               Rick Payne:     Fixed SMP race condition
+               v1.13 9/8/97 Made 'max_interrupt_work' an insmod-settable variable -djb
+               v1.14 10/15/97 Avoided waiting..discard message for fast machines -djb
+               v1.15 1/31/98 Faster recovery for Tx errors. -djb
+               v1.16 2/3/98 Different ID port handling to avoid sound cards. -djb
+               v1.18 12Mar2001 Andrew Morton
+                       - Avoid bogus detect of 3c590's (Andrzej Krzysztofowicz)
+                       - Reviewed against 1.18 from scyld.com

+                               Theory of Operation
+
+I. Board Compatibility
+
+This device driver is designed for the 3Com 3c515 ISA Fast EtherLink XL,
+3Com's ISA bus adapter for Fast Ethernet.  Due to the unique I/O port layout,
+it's not practical to integrate this driver with the other EtherLink drivers.
+
+II. Board-specific settings
+
+The Corkscrew has an EEPROM for configuration, but no special settings are
+needed for Linux.
+
+III. Driver operation
+
+The 3c515 series use an interface that's very similar to the 3c900 "Boomerang"
+PCI cards, with the bus master interface extensively modified to work with
+the ISA bus.
+
+The card is capable of full-bus-master transfers with separate
+lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
+DEC Tulip and Intel Speedo3.
+
+This driver uses a "RX_COPYBREAK" scheme rather than a fixed intermediate
+receive buffer.  This scheme allocates full-sized skbuffs as receive
+buffers.  The value RX_COPYBREAK is used as the copying breakpoint: it is
+chosen to trade-off the memory wasted by passing the full-sized skbuff to
+the queue layer for all frames vs. the copying cost of copying a frame to a
+correctly-sized skbuff.
+
+
+IIIC. Synchronization
+The driver runs as two independent, single-threaded flows of control.  One
+is the send-packet routine, which enforces single-threaded use by the netif
+layer.  The other thread is the interrupt handler, which is single
+threaded by the hardware and other software.
+
+IV. Notes
+
+Thanks to Terry Murphy of 3Com for providing documentation and a development
+board.
+
+The names "Vortex", "Boomerang" and "Corkscrew" are the internal 3Com
+project names.  I use these names to eliminate confusion -- 3Com product
+numbers and names are very similar and often confused.
+
+The new chips support both ethernet (1.5K) and FDDI (4.5K) frame sizes!
+This driver only supports ethernet frames because of the recent MTU limit
+of 1.5K, but the changes to support 4.5K are minimal.

+                               Theory of Operation
+
+I. Board Compatibility
+
+This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
+Adapter.
+
+II. Board-specific settings
+
+None -- PC cards are autoconfigured.
+
+III. Driver operation
+
+The 3c574 uses a Boomerang-style interface, without the bus-master capability.
+See the Boomerang driver and documentation for most details.
+
+IV. Notes and chip documentation.
+
+Two added registers are used to enhance PIO performance, RunnerRdCtrl and
+RunnerWrCtrl.  These are 11 bit down-counters that are preloaded with the
+count of word (16 bits) reads or writes the driver is about to do to the Rx
+or Tx FIFO.  The chip is then able to hide the internal-PCI-bus to PC-card
+translation latency by buffering the I/O operations with an 8 word FIFO.
+Note: No other chip accesses are permitted when this buffer is used.
+
+A second enhancement is that both attribute and common memory space
+0x0800-0x0fff can translated to the PIO FIFO.  Thus memory operations (faster
+with *some* PCcard bridges) may be used instead of I/O operations.
+This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
+
+Some slow PC card bridges work better if they never see a WAIT signal.
+This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
+Only do this after testing that it is reliable and improves performance.
+
+The upper five bits of RunnerRdCtrl are used to window into PCcard
+configuration space registers.  Window 0 is the regular Boomerang/Odie
+register set, 1-5 are various PC card control registers, and 16-31 are
+the (reversed!) CIS table.
+
+A final note: writing the InternalConfig register in window 3 with an
+invalid ramWidth is Very Bad.

+                               Theory of Operation
+
+I. Board Compatibility
+
+This device driver is designed for the 3Com FastEtherLink and FastEtherLink
+XL, 3Com's PCI to 10/100baseT adapters.  It also works with the 10Mbs
+versions of the FastEtherLink cards.  The supported product IDs are
+  3c590, 3c592, 3c595, 3c597, 3c900, 3c905
+
+The related ISA 3c515 is supported with a separate driver, 3c515.c, included
+with the kernel source or available from
+    cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html
+
+II. Board-specific settings
+
+PCI bus devices are configured by the system at boot time, so no jumpers
+need to be set on the board.  The system BIOS should be set to assign the
+PCI INTA signal to an otherwise unused system IRQ line.
+
+The EEPROM settings for media type and forced-full-duplex are observed.
+The EEPROM media type should be left at the default "autoselect" unless using
+10base2 or AUI connections which cannot be reliably detected.
+
+III. Driver operation
+
+The 3c59x series use an interface that's very similar to the previous 3c5x9
+series.  The primary interface is two programmed-I/O FIFOs, with an
+alternate single-contiguous-region bus-master transfer (see next).
+
+The 3c900 "Boomerang" series uses a full-bus-master interface with separate
+lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet,
+DEC Tulip and Intel Speedo3.  The first chip version retains a compatible
+programmed-I/O interface that has been removed in 'B' and subsequent board
+revisions.
+
+One extension that is advertised in a very large font is that the adapters
+are capable of being bus masters.  On the Vortex chip this capability was
+only for a single contiguous region making it far less useful than the full
+bus master capability.  There is a significant performance impact of taking
+an extra interrupt or polling for the completion of each transfer, as well
+as difficulty sharing the single transfer engine between the transmit and
+receive threads.  Using DMA transfers is a win only with large blocks or
+with the flawed versions of the Intel Orion motherboard PCI controller.
+
+The Boomerang chip's full-bus-master interface is useful, and has the
+currently-unused advantages over other similar chips that queued transmit
+packets may be reordered and receive buffer groups are associated with a
+single frame.
+
+With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme.
+Rather than a fixed intermediate receive buffer, this scheme allocates
+full-sized skbuffs as receive buffers.  The value RX_COPYBREAK is used as
+the copying breakpoint: it is chosen to trade-off the memory wasted by
+passing the full-sized skbuff to the queue layer for all frames vs. the
+copying cost of copying a frame to a correctly-sized skbuff.
+
+IIIC. Synchronization
+The driver runs as two independent, single-threaded flows of control.  One
+is the send-packet routine, which enforces single-threaded use by the
+dev->tbusy flag.  The other thread is the interrupt handler, which is single
+threaded by the hardware and other software.
+
+IV. Notes
+
+Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development
+3c590, 3c595, and 3c900 boards.
+The name "Vortex" is the internal 3Com project name for the PCI ASIC, and
+the EISA version is called "Demon".  According to Terry these names come
+from rides at the local amusement park.
+
+The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes!
+This driver only supports ethernet packets because of the skbuff allocation
+limit of 4K.

+ * This driver currently supports Tigon I and Tigon II based cards
+ * including the Alteon AceNIC, the 3Com 3C985[B] and NetGear
+ * GA620. The driver should also work on the SGI, DEC and Farallon
+ * versions of the card, however I have not been able to test that
+ * myself.
+ *
+ * This card is really neat, it supports receive hardware checksumming
+ * and jumbo frames (up to 9000 bytes) and does a lot of work in the
+ * firmware. Also the programming interface is quite neat, except for
+ * the parts dealing with the i2c eeprom on the card ;-)
+ *
+ * Using jumbo frames:
+ *
+ * To enable jumbo frames, simply specify an mtu between 1500 and 9000
+ * bytes to ifconfig. Jumbo frames can be enabled or disabled at any time
+ * by running `ifconfig eth<X> mtu <MTU>' with <X> being the Ethernet
+ * interface number and <MTU> being the MTU value.
+ *
+ * Module parameters:
+ *
+ * When compiled as a loadable module, the driver allows for a number
+ * of module parameters to be specified. The driver supports the
+ * following module parameters:
+ *
+ *  trace=<val> - Firmware trace level. This requires special traced
+ *                firmware to replace the firmware supplied with
+ *                the driver - for debugging purposes only.
+ *
+ *  link=<val>  - Link state. Normally you want to use the default link
+ *                parameters set by the driver. This can be used to
+ *                override these in case your switch doesn't negotiate
+ *                the link properly. Valid values are:
+ *         0x0001 - Force half duplex link.
+ *         0x0002 - Do not negotiate line speed with the other end.
+ *         0x0010 - 10Mbit/sec link.
+ *         0x0020 - 100Mbit/sec link.
+ *         0x0040 - 1000Mbit/sec link.
+ *         0x0100 - Do not negotiate flow control.
+ *         0x0200 - Enable RX flow control Y
+ *         0x0400 - Enable TX flow control Y (Tigon II NICs only).
+ *                Default value is 0x0270, ie. enable link+flow
+ *                control negotiation. Negotiating the highest
+ *                possible link speed with RX flow control enabled.
+ *
+ *                When disabling link speed negotiation, only one link
+ *                speed is allowed to be specified!
+ *
+ *  tx_coal_tick=<val> - number of coalescing clock ticks (us) allowed
+ *                to wait for more packets to arive before
+ *                interrupting the host, from the time the first
+ *                packet arrives.
+ *
+ *  rx_coal_tick=<val> - number of coalescing clock ticks (us) allowed
+ *                to wait for more packets to arive in the transmit ring,
+ *                before interrupting the host, after transmitting the
+ *                first packet in the ring.
+ *
+ *  max_tx_desc=<val> - maximum number of transmit descriptors
+ *                (packets) transmitted before interrupting the host.
+ *
+ *  max_rx_desc=<val> - maximum number of receive descriptors
+ *                (packets) received before interrupting the host.
+ *
+ *  tx_ratio=<val> - 7 bit value (0 - 63) specifying the split in 64th
+ *                increments of the NIC's on board memory to be used for
+ *                transmit and receive buffers. For the 1MB NIC app. 800KB
+ *                is available, on the 1/2MB NIC app. 300KB is available.
+ *                68KB will always be available as a minimum for both
+ *                directions. The default value is a 50/50 split.
+ *  dis_pci_mem_inval=<val> - disable PCI memory write and invalidate
+ *                operations, default (1) is to always disable this as
+ *                that is what Alteon does on NT. I have not been able
+ *                to measure any real performance differences with
+ *                this on my systems. Set <val>=0 if you want to
+ *                enable these operations.
+ *
+ * If you use more than one NIC, specify the parameters for the
+ * individual NICs with a comma, ie. trace=0,0x00001fff,0 you want to
+ * run tracing on NIC #2 but not on NIC #1 and #3.
+ *
+ * TODO:
+ *
+ * - Proper multicast support.
+ * - NIC dump support.
+ * - More tuning parameters.
+ *
+ * The mini ring is not used under Linux and I am not sure it makes sense
+ * to actually use it.
+ *
+ * New interrupt handler strategy:
+ *
+ * The old interrupt handler worked using the traditional method of
+ * replacing an skbuff with a new one when a packet arrives. However
+ * the rx rings do not need to contain a static number of buffer
+ * descriptors, thus it makes sense to move the memory allocation out
+ * of the main interrupt handler and do it in a bottom half handler
+ * and only allocate new buffers when the number of buffers in the
+ * ring is below a certain threshold. In order to avoid starving the
+ * NIC under heavy load it is however necessary to force allocation
+ * when hitting a minimum threshold. The strategy for alloction is as
+ * follows:
+ *
+ *     RX_LOW_BUF_THRES    - allocate buffers in the bottom half
+ *     RX_PANIC_LOW_THRES  - we are very low on buffers, allocate
+ *                           the buffers in the interrupt handler
+ *     RX_RING_THRES       - maximum number of buffers in the rx ring
+ *     RX_MINI_THRES       - maximum number of buffers in the mini ring
+ *     RX_JUMBO_THRES      - maximum number of buffers in the jumbo ring
+ *
+ * One advantagous side effect of this allocation approach is that the
+ * entire rx processing can be done without holding any spin lock
+ * since the rx rings and registers are totally independent of the tx
+ * ring and its registers.  This of course includes the kmalloc's of
+ * new skb's. Thus start_xmit can run in parallel with rx processing
+ * and the memory allocation on SMP systems.
+ *
+ * Note that running the skb reallocation in a bottom half opens up
+ * another can of races which needs to be handled properly. In
+ * particular it can happen that the interrupt handler tries to run
+ * the reallocation while the bottom half is either running on another
+ * CPU or was interrupted on the same CPU. To get around this the
+ * driver uses bitops to prevent the reallocation routines from being
+ * reentered.
+ *
+ * TX handling can also be done without holding any spin lock, wheee
+ * this is fun! since tx_ret_csm is only written to by the interrupt
+ * handler. The case to be aware of is when shutting down the device
+ * and cleaning up where it is necessary to make sure that
+ * start_xmit() is not running while this is happening. Well DaveM
+ * informs me that this case is already protected against ... bye bye
+ * Mr. Spin Lock, it was nice to know you.
+ *
+ * TX interrupts are now partly disabled so the NIC will only generate
+ * TX interrupts for the number of coal ticks, not for the number of
+ * TX packets in the queue. This should reduce the number of TX only,
+ * ie. when no RX processing is done, interrupts seen.

+ * Threshold values for RX buffer allocation - the low water marks for

+
+       This driver is designed for the 3Com 3CR990 Family of cards with the
+       3XP Processor. It has been tested on x86 and sparc64.
+
+       KNOWN ISSUES:
+       *) Cannot DMA Rx packets to a 2 byte aligned address. Also firmware
+               issue. Hopefully 3Com will fix it.
+       *) Waiting for a command response takes 8ms due to non-preemptable
+               polling. Only significant for getting stats and creating
+               SAs, but an ugly wart never the less.
+
+       TODO:
+       *) Doesn't do IPSEC offloading. Yet. Keep yer pants on, it's coming.
+       *) Add more support for ethtool (especially for NIC stats)
+       *) Allow disabling of RX checksum offloading
+       *) Fix MAC changing to work while the interface is up
+               (Need to put commands on the TX ring, which changes
+               the locking)
+       *) Add in FCS to {rx,tx}_bytes, since the hardware doesn't. See
+               http://oss.sgi.com/cgi-bin/mesg.cgi?a=netdev&i=20031215152211.7003fe8e.rddunlap%40osdl.org

-                               Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
-Adapter.
-
-II. Board-specific settings
-
-None -- PC cards are autoconfigured.
-
-III. Driver operation
-
-The 3c574 uses a Boomerang-style interface, without the bus-master capability.
-See the Boomerang driver and documentation for most details.
-
-IV. Notes and chip documentation.
-
-Two added registers are used to enhance PIO performance, RunnerRdCtrl and
-RunnerWrCtrl.  These are 11 bit down-counters that are preloaded with the
-count of word (16 bits) reads or writes the driver is about to do to the Rx
-or Tx FIFO.  The chip is then able to hide the internal-PCI-bus to PC-card
-translation latency by buffering the I/O operations with an 8 word FIFO.
-Note: No other chip accesses are permitted when this buffer is used.
-
-A second enhancement is that both attribute and common memory space
-0x0800-0x0fff can translated to the PIO FIFO.  Thus memory operations (faster
-with *some* PCcard bridges) may be used instead of I/O operations.
-This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
-
-Some slow PC card bridges work better if they never see a WAIT signal.
-This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
-Only do this after testing that it is reliable and improves performance.
-
-The upper five bits of RunnerRdCtrl are used to window into PCcard
-configuration space registers.  Window 0 is the regular Boomerang/Odie
-register set, 1-5 are various PC card control registers, and 16-31 are
-the (reversed!) CIS table.
-
-A final note: writing the InternalConfig register in window 3 with an
-invalid ramWidth is Very Bad.

-       the Department of Energy project number 0274DD06D1 and NLM project
-       number Y1-LM-2015-01.
-
-       This driver is designed for the 3Com 3CR990 Family of cards with the
-       3XP Processor. It has been tested on x86 and sparc64.
-
-       KNOWN ISSUES:
-       *) Cannot DMA Rx packets to a 2 byte aligned address. Also firmware
-               issue. Hopefully 3Com will fix it.
-       *) Waiting for a command response takes 8ms due to non-preemptable
-               polling. Only significant for getting stats and creating
-               SAs, but an ugly wart never the less.
-
-       TODO:
-       *) Doesn't do IPSEC offloading. Yet. Keep yer pants on, it's coming.
-       *) Add more support for ethtool (especially for NIC stats)
-       *) Allow disabling of RX checksum offloading
-       *) Fix MAC changing to work while the interface is up
-               (Need to put commands on the TX ring, which changes
-               the locking)
-       *) Add in FCS to {rx,tx}_bytes, since the hardware doesn't. See
-               http://oss.sgi.com/cgi-bin/mesg.cgi?a=netdev&i=20031215152211.7003fe8e.rddunlap%40osdl.org
