From d7f842442f766db3f39fc5d166ddcc24bf817056 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Tue, 25 Oct 2016 10:32:16 +0300 Subject: [PATCH] mac80211: fix the TID on NDPs sent as EOSP carrier In the commit below, I forgot to translate the mac80211's AC to QoS IE order. Moreover, the condition in the if was wrong. Fix both issues. This bug would hit only with clients that didn't set all the ACs as delivery enabled.
