Hi all, claudio@ suggested to try same setup with FreeBSD. So I've tried FreeBSD and Linux and results are same, 1G BiDi from FS.COM coded for Cisco won't work with Intel 82599 10G card. If I boot FreeBSD and Linux with that sfp in 82599 or X710 card that interface will be disabled at boot and won't show up in OS. On OpenBSD i could see it but mac address is 00:00:00:00:00:00 I've tried all combinations with unsupported_sfp statements for FreeBSD and Linux but I couldn't see that interface in OS. If I put that sfp in card after boot status is no carrier whatever I do, at least on FreeBSD. I'm still playing with Linux.. it seems that I've missed out all football here :) it seems that I've missed out all football here
