I can vouch for the Mellanox ConnectX-4 cards as working well, along
with the Chelsio T5 stuff, both under heavy production usage in both
routing and endpoint cases. In my testing the T5 was a slightly better
option in situations demanding PPS with a higher ceiling and lower cpu
utilization, but they came out essentially in a dead heat when testing for
raw throughput.
