rtl8187: Fix error in setting OFDM power settings for RTL8187L 2009-02-02T17:53:25+00:00 Larry Finger Larry.Finger@lwfinger.net 2009-01-27T18:31:23+00:00 f113ce73199be055550c6ed242f499be208d0b30 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.
