At the same time, apparently, yes. This commit[1] has more clarifications.

I almost missed this one. Anyway, when I wrote that I tried a lot of possible workarounds. Including this suggestion [limit ampdu to tid 0 & 1], but it had no effect, the TX-QoS arbiter just gets stuck :(. ^ permalink raw reply [flat|nested] 7+ messages in thread

It's not only carl9170, it's AR9170 (the chip) . Take a look into the original firmware: <http://git.kernel.org/?p=linux/kernel/git/mcgrof/ar9170-fw.git;a=blob;f=STA/hostif.c;h=aa277d14ee5ec4c222b83975d7dc2d5c66dbf91c;hb=2e3574ce10c74a82047a06b046855de14d969948#l107> 107 /* TxQ number */ 108 //txqNum = (buf[2] >> 13); 109 //if (txqNum > 4) 110 { 111 txqNum = 0; 112 } 113 114 zfDmaPutPacket(&zgTxQ[txqNum], desc); 115 /* Trigger WLAN TX DMA */ 116 zm_wl_dma_trigger_reg = (1 << txqNum); So yes, someone took a shortcut along the way.
