From 0aa419ec6e7b98d485f6c66a62a90965eda3c1bb Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Tue, 18 Oct 2016 23:12:10 +0300 Subject: mac80211: allow the driver not to pass the tid to ieee80211_sta_uapsd_trigger iwlwifi will check internally that the tid maps to an AC that is trigger enabled, but can't know what tid exactly. Allow the driver to pass a generic tid and make mac80211 assume that a trigger frame was received.
