>Description:
trying to put if_ral (and so wlan) to work in ap mode,
when the interface goes up and with an IP number, the sistem panics.

the ratectl struture neede by wlan_amrr
when in mode not client.
A fix follows (must be auditted)
by the gurus...

ifconfig wlan create wlandev ral0 \
wlanmode hostap \
mode 11g
ifconfig wlan0 192.168.1.1
