I tried every setting available including JF. I am currently ditched the 2.5G adapter and am now using ConnectX-3 for both server and workstation and I have zero issues.
I'll give those an endorsement as well, I have ConnectX-3 and ConnectX-2 cards and they're rock solid.

Got the RTL8156B adapter.

No Jumbo Frames. Still huge number of retries. And this is w/ the port Egress limted to 2.4GB via RouterOS.

With Jumbo Frames. Not sure why this performs so much worse.

Will be sticking w/ 10GbE until I can get an actual NBase-T switch I believe.

The one without jumbo frames looks like it negotiated a 1Gbit link not at the 2.5Gbit it should have, limiting things to 2.4Gbit seems odd(or was that a typo?)

Definitely was a 2.5G link. Exact same settings except for jumbo frames. I did limit to 2.4G, I would have increased it to 2.4G if it actually helped. But it can't even saturate 2.4G anyways due to the massive amount of rx mac errors / retries. Pretty sure the issue is that the Ipolex always broadcasts a 10G connection.
