I have managed to own this machine for a few days and it would be nice to
get this card working.
As Manuel suggested, I tried to change/force the media type to 1000baseSX-FDX
and 1000baseSX but to no avail.

I was looking through the code and the code paths in wm_tbi_mediachange()
indicates that there is signal but the link is not up.

I am a bit lost here as to what might be the missing piece.

Since there are two Copper and three Fiber cards on this machine, if I enable
WM_DEBUG, the logs get swamped by the working wm0/wm1 logs.

Any hints on how to go about fixing it ?
