3.13.11.6 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Emmanuel Grumbach <emmanuel.grumb...@intel.com>
commit dc271ee0d04d12d6bfabacbec803289a7072fbd9 upstream.
Firmware folks seem say that this flag can make trouble.
Drop it. The advantage of CTS to self is that it slightly
reduces the cost of the protection, but make the protection
less reliable.
