Hi!
I'm currently working on epic100-fiber support for the SMC9432FTX-SC cards
using the LevelOne LXT970 transceiver (patch will follow in the next days).
I now added the necessary symbols to include/linux/mii.h as I think this is
better then coding the magic numbers in epic100.c.
I also made some little cosmetic changes to this file.
Please see the attached patch and apply or tell me if you won't agree and why.
TIA!
