onoe 6a617566bc Move IEEE 802.11 MAC management functions from awi driver to 
if_ieee80211subr.c, which can be shared between any IEEE 802.11
drivers.
However, most of current working IEEE 802.11b wireless LAN cards
have rich firmware and we cannot have a control to management frames
for such cards.

IBSS creation is now supported for the awi driver.
