[OpenWrt-Devel] [PATCH] [hostap-driver] Major enhancement to hostap.sh script

 * use common openwrt option naming (e.g. sta instead of manged for mode)
 * add support for wds vifs
 * add support for monitor mode
 * add encryption support
 * add antenna selection options
 * add hidden ssid option
 * other minor fixes
