mac80211: make listen_interval be limited by low level driver
This patch makes possible for a driver to specify maximal listen interval The possibility for user to configure listen interval is not implemented yet, currently the maximum provided by the driver or 1 is used. Mac80211 uses config handler to set listen interval for to the driver.
