Correct.
# kldload if_iwi
# aireplay-ng -9 iwi0
# ifconfig iwi0
iwi0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC>
metric 0 mtu 1500
media: IEEE 802.11 Wireless Ethernet autoselect (autoselect <monitor>)
# ifconfig iwi0 -mediaopt monitor
# ifconfig iwi0
iwi0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC>
metric 0 mtu 1500
media: IEEE 802.11 Wireless Ethernet autoselect

hmm.. looks correct to me, am I doing something wrong?
