Subject: [PATCH 3.2 046/152] ath5k: fix hardware queue index assignment

3.2.67-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <nbd@...nwrt.org>

commit 9e4982f6a51a2442f1bb588fee42521b44b4531c upstream.

Like with ath9k, ath5k queues also need to be ordered by priority.
queue_info->tqi_subtype already contains the correct index, so use it
instead of relying on the order of ath5k_hw_setup_tx_queue calls.
