55 | * | |
56 | * | |
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> | |
71 | * | |
72 | * To Do: | |
73 | * | |
74 | * | |
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). | |
