Looking forward at new purchases. I was trying to find the list of native supported PCI devices. The obvious ones I see are avf and rdma. So Intel 710 (now 810?) virtual function and mellanox connectx-(456?)
That's not a lot to choose from, but the mellanox choice is pretty good one I suppose if it works well (e.g. good support for flow director type stuff etc). I'm starting to think that I need to probably stick with DPDK though, I'm also looking into the intel QAT card which gets me back into mbufs overhead anyway. This is a bit sad since the vlib+mbuf overhead is eating bandwidth and/or pps.
