Hello!
Looks like there is no support for 82575GB NIC in OpenBSD kernel. I got something like "Intel PRO/1000 QP (82575GB)" rev 0x02 at pci10 dev 0 function 0 not configured" But I found this link for FreeBSD driver http://downloadcenter.intel.com/Detail_Desc.aspx?ProductID=2874&DwnldID=15815&lang=eng Is there any really quick and easy way to make this driver work in OpenBSD ?
