From: Felix Fietkau <nbd@openwrt.org>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit ad8fdccf9c197a89e2d2fa78c453283dcc2c343f upstream.
The driver passes the desired hardware queue index for a WMM data queue in qinfo->tqi_subtype. This was ignored in ath9k_hw_setuptxqueue, which instead relied on the order in which the function is called.
