[PATCH] [18/223] mac80211: make the beacon monitor available externally

From: Andi Kleen
Date: Sun Dec 12 2010 - 19:23:35 EST


2.6.35-longterm review patch. If anyone has any objections, please let me know.

------------------
From: Luis R. Rodriguez <lrodriguez@xxxxxxxxxxx>

commit d3a910a8e4e846b9a767d35483f4dc7c6de7af82 upstream.

This will be used by other components next. The beacon
monitor was added as of 2.6.34 so these fixes are applicable
only to kernels >= 2.6.34.
