[PATCH] BUG_ON() Conversion in net/tulip/de2104x.c
hi,
this changes if() BUG(); constructs to BUG_ON() which is
cleaner and can better optimized away
One of the if()s contains a call to de_is_running(),
which seems to be safe to replace, but someone with more
knownledge of the code might want to verify this...
