From: Felix Fietkau Date: Sun, 30 Nov 2014 19:38:40 +0000 (+0100) Subject: ath9k_hw: fix hardware queue allocation X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ad8fdccf9c197a89e2d2fa78c453283dcc2c343f;p=linux-beck.git 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.
