> Ideally, it would be better if we had an NE2000 Ethernet card driver; My understanding is that the NE2000 is emulated by practically every single popular x86 emulation platform in existence and its interface is used by a huge variety of older network adapters; if someone feels like making ktcp talk NE2000, it would probably help on the networking side. I am also interested in such NE2000 driver, because the ETH chip on my SBC is an Asix AX88796-L, and according to its datasheet, it claims "register level compatibility with NE2000".
