[PATCH 01/75] nl80211: fix mgmt tx status and testmode reporting for netns

From: Luis Henriques
Date: Wed Aug 14 2013 - 07:02:32 EST


3.5.7.19 -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
namespace.

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.
