The Buffalo device WZR-HP-G450H uses the index 3 for TX gain, which is set to the high_power table currently. Later variants of the router use the same index, but instead refer to the low_ob_db gain table. This is not handled in the driver since there is no way to distinguish board revisions and the high_power table is used (incorrectly) for the newer variants. By default, devices based on AR9300 using the TX gain index 3 have to use the high_power table. To make sure that WZR-HP-G450H is not broken when the high_power table is updated, use a separate array based on information obtained from the platform data. The current situation where only the original variant of WZR-HP-G450H works properly stays unchanged. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.
