    Subject[ 032/108] rtlwifi: rtl8192ce: Fix loss of receive performance
    3.0-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Jingjun Wu <jingjun_wu@realsil.com.cn>

    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.
