I just upgraded from 20.1 latest to 20.7 latest. I'm getting frequent "igb1: link state changed to DOWN" (followed by UP). What worked for me in 20.1 was setting eee_disabled to 1.
The eee_disabled flag does not appear to be supported on 20.7 as when I try to set it using sysctl I get unknown oid. I use "systctl dev.igb.0.eee_disabled=1" (I also have it set in tunables).
I do see what appears to be a new oid, eee_control, but I cannot find documentation on it.
I also see iflib is being used, but cannot find any docs describing how to disable EEE.
I also see em driver supports my Intel card, the i211. I'm unsure if I should be using the em driver over the igb driver, and if so, how to do that.
I appreciate any tips on how to proceed. My router interfaces are quite unstable at the moment.
Edit:
I added the tunable hw.em.eee_setting=0 in the OPNSense GUI. That's my best guess on the fix, but have not found much in my Googling.
For reference, my dmesg for igb0:
My sysctl -A piped through grep eee (all the 'eee' settings were 1 before I set hw.em.eee_setting to 0):
