 * If a fixed configuration is used, the LNA and div bias
 * settings are fixed and the antenna diversity scanning routine
 * is disabled.
 *
 * If a variable configuration is used, a default is programmed
 * in and sampling commences per RXed packet.
 *
 * Since this is called from ar9285SetBoardValues() to setup
 * diversity, it means that after a reset or scan, any current
 * software diversity combining settings will be lost and won't
 * re-appear until after the first successful sample run.
 * Please keep this in mind if you're seeing weird performance
 * that happens to relate to scan/diversity timing.
