From 34d4bc4d41d282a66dafe1b01a7d46bad468cefb Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 27 Aug 2010 12:35:58 +0200 Subject: mac80211: support runtime interface type changes Add support to mac80211 for changing the interface type even when the interface is UP, if the driver supports it. To achieve this * add a new driver callback for switching, * split some of the interface up/down code out into new functions (do_open/do_stop), and * maintain an own __SDATA_RUNNING bit that will not be set during interface type, so that any other code doesn't use the interface.
