ath9k: fix BE/BK queue order
|
||||
|
||||
Hardware queues are ordered by priority. Use queue index 0 for BK, which
|
||||
has lower priority than BE.

ath9k_hw: fix hardware queue allocation
|
||||
|
||||
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.
