From e2af3fabedbfc84fcecc7337cd4f0f031a51fa63 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Wed, 22 Feb 2017 19:35:10 +0200 Subject: [PATCH] iwlwifi: mvm: map cab_queue to different txq_id cab_queue can now get bigger than u8, since in TVQM we will support 512 queues.. Support it by maintaining internal mapping between the actual number and mac80211 queue (IWL_MVM_DQA_GCAST_QUEUE). For pre-a000 the internal queue will be the same as the mac80211 queue.
