Setting the flag on a down interface is still allowed, so\nthe driver is handed a monitor with no queue. ath9k dereferences it:\n\n BUG: kernel NULL pointer dereference, address: 0000000000000066\n RIP: 0010:ath_tx_node_init+0x49/0x170 [ath9k]\n ath9k_add_interface+0x10c/0x140 [ath9k]\n drv_add_interface+0x54/0x250 [mac80211]\n ieee80211_do_open+0x32f/0x800 [mac80211]\n\nReached with CAP_NET_ADMIN by \"iw dev X set monitor active\" followed by\n\"ip link set X up\".
