- * 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)
|
|
|
- * 060611 v1.02: slight cleanup: email addresses, driver modernization.
|
|
|
- * Bugs:
|
|
|
- * - not SMP-safe (no locking of I/O accesses)
|
|
|
- * - 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 say 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.ko io=0x300 irq=5
