[ 037/102] nl80211: fix mgmt tx status and testmode reporting for netns

From: Greg Kroah-Hartman
Date: Thu Aug 08 2013 - 22:16:41 EST

3.10-stable review patch. If anyone has any objections, please let me know.


From: Michal Kazior <michal.kazior@xxxxxxxxx>

commit a0ec570f4f69c4cb700d743a915096c2c8f56a99 upstream.

These two events were sent to the default network

This caused AP mode in a non-default netns to not
work correctly. Mgmt tx status was multicasted to
a different (default) netns instead of the one the
AP was in.
