From d66bd0c4840abc2d1793a1bf598ecc554d2376e1 Mon Sep 17 00:00:00 2001 From: Haim Dreyfuss Date: Fri, 15 Nov 2019 09:28:17 +0200 Subject: [PATCH] iwlwifi: mvm: don't skip mgmt tid when flushing all tids There are various of flows which require tids flushing (disconnection, suspend, etc...). Currently, when the driver instructs the FW to flush he masks all the data tids(0-7). However, the driver doesn't set the management tid (#15) which cause the FW not to flush it. When the FW tries to remove the mgmt queue he throws an assert since it is not an empty queue. instead of just set only the data tids set everything and let the FW ignore the invalid tids.
