This\ncauses a sub-interface to be created with no IEEE80211_SDATA_IN_DRIVER bit\nset because the monitor interface is in the cooked state and it takes\nprecedence over all other states. When the interface is then being deleted\nthe kernel calls WARN_ONCE() from check_sdata_in_driver() because of missing\nthat bit.\n\nFix this by rejecting MONITOR_FLAG_COOK_FRAMES if it is set along with\nother flags.\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."
