11 | * Sources: | ||
12 | * Donald Becker's "skeleton.c" | ||
13 | * Crynwr ni5010 packet driver | ||
14 | * | ||
15 | * Changes: | ||
16 | * v0.0: First test version | ||
17 | * v0.1: First working version | ||
18 | * v0.2: | ||
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. | ||
26 | * Bugs: | ||
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. | ||
30 | * | ||
31 | * To do: | ||
32 | * Fix all bugs :-) | ||
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) | ||
40 | * | ||
41 | * Compile with: | ||
42 | * gcc -O2 -fomit-frame-pointer -m486 -D__KERNEL__ \ | ||
43 | * -DMODULE -c ni5010.c | ||
44 | * | ||
45 | * Insert with e.g.: | ||
46 | * insmod ni5010.ko io=0x300 irq=5 | ||
