The driver is issueing "incorrect" checksums during transmissions from the vge device, as observed from tcpdump -vvv. Hello, We have had success with many of the Via EN12000E motherboards and FreeBSD. These have the VT6122 chip on VIA VT8237R-series South Bridge. We have used various versions of 6.0-6.2 and 7.0-STABLE and it has always performed flawlessly at 100m and gigabit speeds to various switches. I wonder if you have are experiencing an incompability with your switch or the device at the other end of the cable? That kind of behaviour smells like a link-level issue to me. - Andrew
