I see PHY and MAC split as advantageous because it allows code reuse and better testing. The main thing I'd like to see is PHY device tests using tests/libqtest.h. If someone wants to implement it, great. It would make it easier to add more NIC models in the future. Regarding SOCification and busses, I'm not sure. Is it okay to just say a NIC has-a PHY (i.e. composition)? Stefan
