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.
