12 * Donald Becker's "skeleton.c"
13 * Crynwr ni5010 packet driver
16 * v0.0: First test version
17 * v0.1: First working version
19 * v0.3->v0.90: Now demand setting io and irq when loading as module
20 * 970430 v0.91: modified for Linux 2.1.14
21 * v0.92: Implemented Andreas' (better) NI5010 probe
22 * 970503 v0.93: Fixed auto-irq failure on warm reboot (JB)
23 * 970623 v1.00: First kernel version (AM)
24 * 970814 v1.01: Added detection of onboard receive buffer size (AM)
25 * 060611 v1.02: slight cleanup: email addresses, driver modernization.
27 * - not SMP-safe (no locking of I/O accesses)
28 * - Note that you have to patch ifconfig for the new /proc/net/dev
29 * format. It gives incorrect stats otherwise.
33 * Move some stuff to chipset_init()
34 * Handle xmt errors other than collisions
35 * Complete merge with Andreas' driver
36 * Implement ring buffers (Is this useful? You can't squeeze
37 * too many packet in a 2k buffer!)
38 * Implement DMA (Again, is this useful? Some docs say DMA is
39 * slower than programmed I/O)
