See: https://en.wikipedia.org/wiki/Duplex_mismatch If a device is set to a fixed speed and media setting, a connecting device configured to perform auto-negotion may detect the speed, but must assume half-duplex mode. This may not be the expected behavior today, but is what the standard deman= ds. Either use auto-negotiation on both interfaces or set both to matching mode= s. --=20 You are receiving this mail because: You are the assignee for the bug.=
