-Subject: [PATCH] ath9k: Enable HW queue control only for MCC
-
-Enabling HW queue control for normal (non-mcc) mode
-causes problems with queue management, resulting
-in traffic stall. Since it is mainly required for
-fairness in MCC mode, disable it for the general case.

-Bug: https://dev.openwrt.org/ticket/18164
