Ok, thanks. FWIW there is a large body of 802.11-related code that
should be lifted form various parts of the src tree into a lib80211 or
similar. For example there is now an XML database of regulatory domain
information that ifconfig uses. UI apps could easily want to use this
info along w/ many other bits that are mostly used by ifconfig at the
moment.
I am happy to work w/ anyone that's interested in this.
