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.

Plus Mellanox introduced the SwitchDev capability which provides for 
offloading flow management to the hardware.
