Hi Evgeniy, One of the questions I had was indeed how to troubleshoot this. Nothing is in dmesg or messages that is out of the ordinary, I can not find anything that changes on the interface or netstat.
Until the 18th of March this machine was running FreeBSD, without any issues. I moved from 9.3-RELEASE-pXX to OpenBSD 5.8. There are still 2 machines of the same type that are running FreeBSD 9.3 without any issues. I do know there are issues in FreeBSD 10 with this NIC which haven't been resolved. But they have primarily to do that the driver is not loading. The thing that is strange is that it works after reboot, I can ping an IP. But as soon as I run ftp or pkg_add for example, it stops working.
