Sort of. A link between the endpoints is established, but then it stalls and fails after a "connection reset". > Did both ends agree on established speed/duplex? Yes, they did. > What speed/duplex was chosen by msk(4)? 10/100MBit and GBit duplex, respectively. > Forcing speed/duplex have any effects? Not sure, but using a 100MBit and 1GBit connection yields the same results, whereas before I just claimed it was just gigabit connections. > Turning off checksum offload or TSO have any effects?

I'm connecting via a switch and it works perfectly fine via 7-RELENG with amd64. > tcpdump data for a broken connection might be help too. Ok. More help on trying to setup everything to debug this issue would be helpful. FWIW, the issue might be that the MTU doesn't match for Windows and FreeBSD (I remember reading that somewhere a while back)... unfortunately, my router speaks this MTU (1464?) so connections via msk don't work properly anymore on 8-CURRENT.
