Thanks for the reply.

Take a look at the Mellanox ConnectX 5 series of cards. They handle
DPDK, PVRDMA (basically SR-IOV that allows live migration between
hosts), and can even process packets within the NIC for some

From what I can tell, SR-IOV/PVRDMA aren't really useful for me in
building a router that wont be doing any virtualization.

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

The slidedeck for the presentation is here:

It's heavily targeting virtualised workloads but some of the feature sets apply to bare-metal uses too.

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