mac80211: reject extra IEs for probe request when hw_scan
We cannot currently hand off extra IEs to hw_scan, so reject configuring extra IEs for probe request frames when hw_scan is set. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Cc: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>
