Hmm, this looks like a lot of the stats reported by the 80211stats 
program; David probably told me he'd done this but I forgot.  I've not 
merged the report to ifconfig on other systems because I'm not sure it 
belongs there.  OTOH I have done many things to freebsd's ifconfig that 
I miss already on netbsd.  At the very least I'd like to see ifconfig 
w/o any options work like the -a flag instead of printing a usage message.
