Thanks Jack! The problem is that right now the card is connected to a passive tap and there is no AN. When I do ifconfig ix0 down && ifconfig ix0 up, the multispeed fiber logic goes into action but a link never happens (it does for 10G but there is no AN on 10G so this is expected). (I tried various settings for LMS bits in AUTOC but I could not get a link - the datasheet is very vague - actually come to think of it, I dont think I tried setting it to 0 which is 1G which maybe the trick) -aps
