call for help w/ vap support scripts

[Sam Leffler]

I'm preparing the multi-bss/vap wireless code for commit to HEAD but 
need help w/ the rc scripts (and devd glue) to make this happen.  With 
vaps the underlying device is no longer used directly; instead you must 
clone a vap ifnet before you can do things like associate to an ap.  For 
example,

ifconfig wlan create wlandev ath0 wlanmode sta

will create a wlanX device that operates in station mode.  This doesn't 
work with the existing rc support so we need changes.  If you're 
interested in working on this please contact me directly.

Note I am not interested in suggestions of the sort "why don't you 
auto-create wlanX's for each device".  I've been down that road (the vap 
code is nearly 4 years old) and that's a disaster.
