3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jingjun Wu <[email protected]> commit a9b89e2567c743483e6354f64d7a7e3a8c101e9e upstream. Driver rtl8192ce when used with the RTL8188CE device would start at about 20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the symptoms is that the AP would need to retransmit each packet 4 of 5 times before the driver would acknowledge it. Recovery is possible only by unloading and reloading the driver. This problem was reported at https://bugzilla.redhat.com/show_bug.cgi?id=770207. The problem is due to a missing update of the gain setting.
