This sequence of events causes loss of connectivity:
<plug in>
<associate as normal in managed mode>
ifconfig eth7 down
iwconfig eth7 mode monitor
ifconfig eth7 up
ifconfig eth7 down
iwconfig eth7 mode managed
<associate as normal>
At this point you are associated but TX does not work. This is because
the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit.
Fix this by unsetting the hard_start_xmit handler in ieee80211_if_reinit. It
will then be reinitialised to the default (ieee80211_subif_start_xmit) in
ieee80211_if_set_type.
