Date: Thu, 4 Oct 2007 12:33:43 +0100 (BST) From: Daniel Drake <dsd@...too.org> To: linville@...driver.com Cc: linux-wireless@...r.kernel.org Subject: [PATCH] mac80211: Fix TX after monitor interface is converted to managed 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.
