But could be useful to quickly get the driver name of physical devices. > Given that currently on FreeBSD the easiest way to tell if something is a physical device is by checking the *absence* of groups, this would only really be acceptable if we add an "egress" group like OpenBSD does, in addition to the driver name. If we can't do that, then I think Mike's solution with having the driver (and unit) as a separate category would be preferable. Unrelatedly, I don't see anything in ure(4) mentioning that if_ure devices will be named "ue". Don't we usually document such deviation from the norm? Kind regards, Mina
