Related question: are there any 100Mbit NICs with cpu's onboard?
Yes, but the only ones I've seen to date are magic and do special
things (like VPN or hardware crypto). I'm not sure without 'magic'
requirements there is much point for 100M on modern hardware.
Not affordable and whilst moving some of the IP stack onto the card
(I think this is what are alluding to) would be extremely non-trivial
especially if you want all the components (host OS, multiple networks
cards) to talk to each other asynchronously and you would all have to
deal with buggy hardware that doesn't like doing PCI-PCI transfers
and such like.
That said, it would be an extemely neat thing to do from a technical
perspective, but I don't know if you would ever get really good
performance from it.
