Thanks, but I do not know if iflib is loaded. I simply burn the iso from
https://download.freebsd.org/ftp/releases/amd64/amd64/ISO-IMAGES/12.0/FreeBSD-12.0-RELEASE-amd64-dvd1.iso
on DVD and install this OS with default settings (I use auto ZFS on whole disk). Thats all.
I'm still novice user in BSD world. I can add that this computer simply work on Debian 9 
or Windows 7 without any problem with this network card. So the question is why this network card 
do not works on fresh install on FreeBSD 12.0?

Thanks in advance.
