The X520 and X540 are among the list; I’ve tested the driver with a pair of X520 10G-baseT adapters.

The net.inet.tcp.sosend_agglim sysctl should not be used blindly; setting it to 12 will increase latency on 1Gb/s connections.
Sepherosa Ziehau is planning to make this sysctl device specific in the future.

Note that the improvement happens only in single-stream situations, so it may not matter if you’re dealing with a situation where you have multiple connections adding up to fill the bandwidth on a 10G card.

Francois is on #dragonflybsd EFNet IRC frequently; that may be an easy way to follow up.
