From 68629c6133304f286a1f0c12d9aa8071a639f076 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 3 Nov 2011 09:59:39 +0100 Subject: mac80211: preserve EOSP in QoS header Janusz reported that the EOSP bit in mac80211 was getting cleared all the time. I had not found this since I tested uAPSD with a device that always set the bit itself. Preserve the bit when building the QoS header.
