Hi Micah, 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 models. They did a fantastic presentation at AusNOG 2019 which showed off a lot of the features. We tried some out with Vmware and could get 20Gbps throughput (limited by the 2x 10G NICs we had configured) to a VM running Linux with DPDK+VPP.
The slidedeck for the presentation is here: https://www.ausnog.net/sites/default/files/ausnog-2019/presentations/1.9_Rhod_Brown_AusNOG2019.pdf It's heavily targeting virtualised workloads but some of the feature sets apply to bare-metal uses too.

It needs to be able to do XDP, multiqueues, have good in-kernel driver support and be able to handle 10Gbe with good offloading for dealing with high packets per second. What features should I be looking for to really optimize things for a three transit setup, with full tables. Something like the Intel XL710-QDA2 card maybe? -- micah
