Set disable-flow-comtrol
Check interfaces trafic atatiatic but dont have dropped packets 0

And when i commit interface settings i getting this error

could not set flowcontrol for eth3
could not set flowcontrol for eth2

Hello @sponner , could you provide sudo dmesg output, it looks like HW issue. I saw a similar issue with non-original Intel NICs
Also check output of the command

 show interfaces ethernet ethX transceiver 

i send on private message

Yes, I looked through it already. There no kernel messages reported about HW issue.
