From fe959c7b20495fe05de5f65ea0968a7b128afa9e Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Thu, 11 Jul 2019 21:44:42 +0300 Subject: iwlwifi: mvm: use the new session protection command The firmware has now a new session protection command. This new API allows the firmware to manage the protection needed for association. It'll also remove the event when the association is complete.

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.
