FreeBSD vr network card issues
Sort of a note to self for the next time I bump into a very annoying issue with network cards that use the VIA Technologies Rhine I/II/III controller chips on network cards like the quite popular dlink (shows up under vrX in ifconfig -a) is that when you start binding multiple IP addresses on a vr card a few seconds later the card stops working.
Turns out there is a bug of sorts with the FreeBSD vr driver which needs some fixing so moral of the story for the moment is not using vr based network cards till this is fixed.
