And for general knowledge: the Linux TAP dev, nor the cs8900a, require any sort of FCS/CRC. So says the contiki c64 src that works on Jim's c64 nic. Hooking this all up to fuzix will take some time. I'm scratching my head over kernel/net buffering. Weird magic backing files. Kernel events. And network events. ever grok a unix socket struct? Bleh!
