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 Signed-off-by: Vasilis Tsiligiannis <[email protected]>
