cfg80211/nl80211: add interval attribute for scheduled scans
Introduce NL80211_ATTR_SCHED_SCAN_INTERVAL as a required attribute for NL80211_CMD_START_SCHED_SCAN. This value informs the driver at which intervals the scheduled scan cycles should be executed. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
