cfg80211: add feature to hold bss
In beacon filtering there needs to be a way to not expire the BSS even when no beacons are received. Add an interface to cfg80211 to hold BSS and make sure that it's not expired. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
