Yeah, uh, just to clarify this, that's what happens when you use a really old janky Chelsio PCIe 1.1 card from 2006, and replace it with a much newer PCIe 2.0 card from 2010.Just received 2x of my Solarflare SFN5122F to replace my old 10G card Chelsio cc2-s320e-sron SFP+ on Supermicro X10SL7-F ( TrueNAS Core 12 Beta) and X9SRL-F ( FreeNAS 11.3-U4). I can confirm they all work well without any loading drivers or anything just plug and play. Solarflare gives you almost full speed while Chelsio gets you half the speed.
I do ask that people do not make generalizations if they're going to post in my thread here.
The highly recommended Chelsio T520-CR is a PCIe 3.0 card and will beat on the 5122.
The PCIe 3.0 SFN6122F (also PCIe 3.0) has been available on eBay for $20-$40 for at least a few years. I haven't tried it on FreeNAS as bare metal but don't have any reason to think it wouldn't work. I use these under ESXi and they're great, they work as well as the X520 (PCIe 2.0) and they generate less heat.
