+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
