From 93f436e2c7feacb04a21bbfb984a7afd87fb4623 Mon Sep 17 00:00:00 2001 From: Liad Kaufman Date: Mon, 31 Aug 2015 13:41:26 +0300 Subject: [PATCH] iwlwifi: mvm: set sta_id in SCD_QUEUE_CONFIG cmd Set the correct sta_id in the SCD_QUEUE_CONFIG command sent to the FW when enabling/disabling queues. This is needed in DQA-mode to allow the FW to associate between queue and STA. In case the queue isn't connected to a specific station but rather is a static "generic" queue - the sta_id should be set to 0x10 (max supported STA is 0x0f).
