Re: ifconfig -G broken in 14.2?

....mumbling to myself...

$ ifconfig -l
em0 lo0
$ ifconfig -a -G lo
em0: flags=1008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,LOWER_UP>
metric 0 mtu 1500

I failed to realize -G works when used in conjunction with -a, just
not alone or with -l (which is consistent with the man page). Sorry
for the noise.
