Can't get X540-AT2 quad port NIC to negotiate at 10Gb

[mtlater]

I've been trying to get a X540-AT2 NIC to negotiate at 10Gb to a 10GbE switch (MokerLink 10G080GPTM) but I can only get 1Gb speeds with a 5ft cat6a cable. I've looked through some other posts here but none have solved the issue for me. I'm wondering what I'm missing. Some relevant data:

Port config in switch:

 

[fba]

Try manually setting speed of the nic:
ethtool -s enp69s0f0 autoneg on speed 10000 duplex full
and on the switch, if possible.

Personally: I will never ever use again 10G over copper. Too many issues with incompatibilities between ports/sfp, crosstalk between neighbouring ports, overheating sfp modules, port flapping.... It is just not worth the trouble.

I appreciate the response. Even when I try manually setting the speed at both the NIC and the switch, the connection just drops. I wonder if it could be a driver issue with the NIC.
