If I lower the speed to 100Mb/s I don't have rx errors anymore *BUT*
when using dhcp after a while the network doesn't work anymore:
64 bytes from 8.8.8.8: icmp_req=590 ttl=47 time=61.7 ms
64 bytes from 8.8.8.8: icmp_req=591 ttl=47 time=62.0 ms
64 bytes from 8.8.8.8: icmp_req=592 ttl=47 time=62.0 ms
ping: sendmsg: Network is unreachable
ping: sendmsg: Network is unreachable
ping: sendmsg: Network is unreachable
I have no problems with dhcp using wifi or other NICs.
