re(4) problems with GA-H77N-WIFI

[Oliver Fromme]

I'm sorry for the late reply.  I didn't have much time
this week to investigate this issue.  At the moment I
implemented a work-around with an additional switch using
VLANs, but I'd really like to get the second NIC working.

No.  I can only see them locally in tcpdump, but they never
hit the wire.

No, it doesn't.

re0: CMD 0x0c
re0: link state changed to UP
re0: link state changed to DOWN
re1: link state changed to UP
re1: link state changed to DOWN
re1: CMD 0x0c
re1: link state changed to UP
re0: CMD 0x0c
re0: link state changed to UP
re1: link state changed to DOWN

I always seem to get 0x0c for both re0 and re1.

Best regards
