Problems with Atheros card and hostpd

[Boris Kochergin]

Multi-BSS support in 8.0 means that you first need to create a wlan 
pseudo-device, and run hostapd with that. The rc.conf lines look like this:

wlans_ath0="wlan0"
create_args_wlan0="wlanmode hostap"
ifconfig_wlan0="ssid networkname media autoselect up"
