It could be worthwhile to check if lance (Am7990) and pcnet (Am79C970A)
drivers could be merged. This was discussed briefly some years ago:
http://lists.gnu.org/archive/html/qemu-devel/2004-10/msg00364.html
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?
