According to the comment in ath_cmn_process_fft() this doesn't seem to be necessary for all chips: 515 /* AR9280 and before report via ATH9K_PHYERR_RADAR, AR93xx and newer 516 * via ATH9K_PHYERR_SPECTRAL. Haven't seen ATH9K_PHYERR_FALSE_RADAR_EXT 517 * yet, but this is supposed to be possible as well. 518 */ 519 if (rs->rs_phyerr != ATH9K_PHYERR_RADAR && 520 rs->rs_phyerr != ATH9K_PHYERR_FALSE_RADAR_EXT && 521 rs->rs_phyerr != ATH9K_PHYERR_SPECTRAL) 522 return 0; Michał _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
