Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
* Sources:
|
|
* Donald Becker's "skeleton.c"
|
|
* Crynwr ni5010 packet driver
|
|
*
|
|
* Changes:
|
|
* v0.0: First test version
|
|
* v0.1: First working version
|
|
* v0.2:
|
|
* v0.3->v0.90: Now demand setting io and irq when loading as module
|
|
* 970430 v0.91: modified for Linux 2.1.14
|
|
* v0.92: Implemented Andreas' (better) NI5010 probe
|
|
* 970503 v0.93: Fixed auto-irq failure on warm reboot (JB)
|
|
* 970623 v1.00: First kernel version (AM)
|
|
* 970814 v1.01: Added detection of onboard receive buffer size (AM)
|
|
* Bugs:
|
|
* - None known...
|
|
* - Note that you have to patch ifconfig for the new /proc/net/dev
|
|
* format. It gives incorrect stats otherwise.
|
|
*
|
|
* To do:
|
|
* Fix all bugs :-)
|
|
* Move some stuff to chipset_init()
|
|
* Handle xmt errors other than collisions
|
|
* Complete merge with Andreas' driver
|
|
* Implement ring buffers (Is this useful? You can't squeeze
|
|
* too many packet in a 2k buffer!)
|
|
* Implement DMA (Again, is this useful? Some docs says DMA is
|
|
* slower than programmed I/O)
|
|
*
|
|
* Compile with:
|
|
* gcc -O2 -fomit-frame-pointer -m486 -D__KERNEL__ \
|
|
* -DMODULE -c ni5010.c
|
|
*
|
|
* Insert with e.g.:
|
|
* insmod ni5010.o io=0x300 irq=5
