>Description:
vge devices won't autonegotiate to gigabit speeds. When forced to gigabit media with ifconfig vge0 media 1000baseTX, ifconfig reports the status as "no carrier."
This problem is documented here: http://forums.freebsd.org/showthread.php?t=1637
Has been discussed on the mailing list here: http://lists.freebsd.org/pipermail/freebsd-current/2008-April/thread.html#start
And is an open bug in OpenBSD: bug ID 5978
>How-To-Repeat:
Boot a computer with a vge interface. ifconfig will report 100baseTX, even if the port is connected to a 1000baseT switch.
