-/* ni5010.c: A network driver for the MiCom-Interlan NI5010 ethercard.
- *
- * Copyright 1996,1997,2006 Jan-Pascal van Best and Andreas Mohr.
- *

- * The authors may be reached as:
- * janpascal@vanbest.org andi@lisas.de
- *
- * 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)
- * 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
