I count 2:1 votes. So "positive feature flag" it is. BTW: I added rt2x00 project maintainers to the CC, because If I'm not totally wrong, this patch _reduces_ some PS features of rt2x00. This is because not all of rt2x00 supported & PS-capable/enabled devices return a proper tx_status and therefore these devices will be the most affected AFAICT. Any word from you guys? Or have you scrubbed the PS features already? Regards, Chr
