Thanks a lot! Maybe Oleksij has some more ideas on > that. ath9k_htc has it own rate controller insight of firmware. We wont to move this functionality to the host and use minstreal-rt, but currently this project is not started and currently there is no clear start time :( Beside, there are more problems with FWs rate controller. David, if you need to fix this bug, i would you suggest you to investigate in firmware. I will help you as match as i can. -- Regards, Oleksij -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
