From e2d389b5aa3741431fc89fca993b7818545dc0f1 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Fri, 17 Oct 2014 07:40:18 +0530 Subject: ath9k: Check for pending frames properly Pending frames in the driver can be present either in the HW queues or SW. ath9k_has_pending_frames() currently checks for the HW queues first and then checks if any ACs are queued in the driver. In MCC mode, we need to check the HW queues alone, since the SW queues are just marked as 'stopped' - they will be processed in the next context switch. But since we don't differentiate this now, mention whether we want to check if there are frames in the SW queues. * The flush() callback checks both HW and SW queues. * The tx_frames_pending() callback does the same. * The call to __ath9k_flush() in MCC mode checks HW queues alone.
