It could be worthwhile to check if lance (Am7990) and pcnet (Am79C970A)
drivers could be merged. This was discussed briefly some years ago:

Yes, a quick look shows 79c970a has one rx/tx buffer management mode which
is software-compatible with 7990 chip (SWMODE=0) There may be more
backward-compatibility bits to be unified. Anyone? :)

Looks like only 32-bit modes are implemented in pcnet.c and endianness issues should be checked.

The files could be reorganised to for example pcnet-common.c, pcnet-pci.c, and pcnet-lance.c or just throw everything together with small performance penalty and unwanted code for both lance and pcnet. Opinions?
