    Subject[patch 30/32] rtl8187: Fix error in setting OFDM power settings for RTL8187L
    2.6.27-stable review patch.  If anyone has any objections, please let us know.

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

    From: Larry Finger <Larry.Finger@lwfinger.net>

    commit eb83bbf57429ab80f49b413e3e44d3b19c3fdc5a upstream.

    After reports of poor performance, a review of the latest vendor driver
    (rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken.

    A difference was found in the code used to index the OFDM power tables. When
    the Linux driver was changed, my unit works at a much greater range than
    before. I think this fixes Bugzilla #12380 and has been tested by at least
    two other users.
