From c80eb570f8ce188e92a1693774a24d0f227985b5 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Thu, 12 Jan 2017 15:43:57 +0200 Subject: [PATCH] iwlwifi: mvm: tell the firmware about the U-APSD parameters Newer firmware versions will be able to handle all the WMM-PS flows internally when we act as a GO. The firwmare relies on the fact that the drivers puts frames for different peers in different queues (DQA) to achieve this. The driver will not be aware of the power state of the peers anymore. Tell the firmware about the WMM-PS parameters of earch peer that connects to us so that it can know what are the trigger-enabled ACs, the delivery-enableds ACs and the Service Period length. This API change is backward compatible since older firmware versions will simply ignore the newly added values. Since we don't support ieee80211 TSPECs for now, just copy the trigger-enabled ACs to the delivery enabled ones.
