RE: Linux router network cards

[Jean St-Laurent via NANOG <nanog () nanog org>]

Chelsio cards are probably what you are looking for.

https://www.chelsio.com/terminator-6-asic/

It's closer to an asic than a traditional nic as the router/firewall rules
are pushed directly into the hardware.

I don't know how good they are with linux and they seem to be compatible.

You will need to mess around a bit and fiddle here and there. If you don't
mind using FreeBSD instead of linux, you could achieve a smoother and more
integrated experience.

Thanks for the reply.

If the card can do DPDK, can it do XDP?

Yeah, this wont be a virtualized environment, just a router passing packets,
dropping them, handling bgp and collecting flows.
