"uname -a" is probably the most general answer, as most FreeBSD NIC drivers don't have individualized version #s, aside from the OS version itself.

The sysctl tree under dev for a particular device, ie, "sysctl dev.bce", "sysctl dev.em", etc will return more information which might include a vendor-specific driver version #...
