57 * 12/10/99 - Alpha Release 0.1.0
58 * First release to the public
59 * 03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
60 * malloc free checks, reviewed code. <alan@redhat.com>
61 * 03/13/00 - Added spinlocks for smp
62 * 03/08/01 - Added support for module_init() and module_exit()
63 * 08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
64 * calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
65 * 11/05/01 - Restructured the interrupt function, added delays, reduced the
66 * the number of TX descriptors to 1, which together can prevent
67 * the card from locking up the box - <yoder1@us.ibm.com>
68 * 09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
69 * 11/13/02 - Removed free_irq calls which could cause a hang, added
70 * netif_carrier_{on|off} - <yoder1@us.ibm.com>
75 * If Problems do Occur
76 * Most problems can be rectified by either closing and opening the interface
77 * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
78 * if compiled into the kernel).
