3.3-stable review patch. If anyone has any objections, please let me know.
------------------ From: Larry Finger <[email protected]> commit 643c61e119459e9d750087b7b34be94491efebf9 upstream. In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver rtl8192ce are reported. One fix (commit a9b89e2) has already been applied, and it helped, but the maximum RX speed would still drop to 1 Mbps. As in the previous fix, the initial gain was determined to be the problem; however, the problem arises from a setting of the gain when scans are started. Driver rtl8192de also has the same code structure - this one is fixed as well.
