20080420:
         The 802.11 wireless support was redone to enable multi-bss
         operation on devices that are capable.  The underlying device
         is no longer used directly but instead wlanX devices are
         cloned with ifconfig.  This requires changes to rc.conf files.
         For example, change:
                 ifconfig_ath0="WPA DHCP"
         to
                 wlans_ath0=wlan0
                 ifconfig_wlan0="WPA DHCP"
         see rc.conf(5) for more details.  In addition, mergemaster of
         /etc/rc.d is highly recommended.  Simultaneous update of userland
         and kernel wouldn't hurt either.

         As part of the multi-bss changes the wlan_scan_ap and wlan_scan_sta
         modules were merged into the base wlan module.  All references
         to these modules (e.g. in kernel config files) must be removed.
