zd1211rw: Fix TX status reporting in order to have proper rate control
First, we reduce the number of hardware retries to 0 (ie 2 real retries
for each rate). Next, when we report the retries to mac80211, we always
report a retry count of 1 (it seems to be 2 in fact, but using 2 seems
to lead to wrong performance for some reason). We use a state machine to
determine the real fate of a packet based on the 802.11 ACK and what the
Zydas hardware is saying when a real retry occurs. The real retry rates
are encoded in a static array. It has been tested with both zd1211 and
zd1211b hardware. Of course, since the Zydas hardware is not reporting
retries accurately, we are just doing our best in order to get the best
performance (ie higher throughput).

mac80211: Learn about mesh portals from multicast traffic
Mesh portals proxy traffic for nodes external to the mesh. When a
proxied frame is received by a mesh interface, it should update its mesh
portal table. This was only happening for unicast frames. With this
change we also learn about mesh portals from proxied multicast frames.

wl1271: Workaround for reference clock setting on boot.
If the 38.4MHz reference clock is configured to the firmware, it crashes
on boot. Configuring an experimental 38.4MHz in XTAL mode allows the
firmware to boot, and everything appears to work.

iwlwifi: use paged Rx
This switches the iwlwifi driver to use paged skb from linear skb for Rx
buffer. So that it relieves some Rx buffer allocation pressure for the
memory subsystem. Currently iwlwifi (4K for 3945) requests 8K bytes for
Rx buffer. Due to the trailing skb_shared_info in the skb->data,
alloc_skb() will do the next order allocation, which is 16K bytes. This
is suboptimal and more likely to fail when the system is under memory
usage pressure. Switching to paged Rx skb lets us allocate the RXB
directly by alloc_pages(), so that only order 1 allocation is required.
It also adjusts the area spin_lock (with IRQ disabled) protected in the
tasklet because tasklet guarentees to run only on one CPU and the new
unprotected code can be preempted by the IRQ handler. This saves us from
spawning another workqueue to make skb_linearize/__pskb_pull_tail happy
(which cannot be called in hard irq context).
Finally, mac80211 doesn't support paged Rx yet. So we linearize the skb
for all the management frames and software decryption or defragmentation
required data frames before handed to mac80211. For all the other frames,
we __pskb_pull_tail 64 bytes in the linear area of the skb for mac80211
to handle them properly.

wl1271: remove unnecessary joins and join only when the bssid changes
We were using the join command to change some settings when the stack asked
us to do it. In many cases they were not needed (and could cause potential
problems), so they were removed. In other cases there are ACX commands that
can be used instead of using join to reconfigure.

wl1271: use acx_rx_config instead of join when updating filters
We shouldn't use a join command to change the filter settings while
associated. The right way to do it is to use ACX_RX_CFG.

wl1271: Remove outdated SPI functions
With the change to the new firmware, there was a change to firmware memory
partitioning. Along with that change, the translation of all partitions was
unified, and separate functions for reg and mem access became unnecessary.
