From: Stanislaw Gruszka <sgruszka@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 8834d3608cc516f13e2e510f4057c263f3d2ce42 upstream.
When disable beaconing we clear register with beacon and newer set it
back, what make we stop send beacons infinitely.
