From 83cf639325d2819ac04cae9c086b7062da60b762 Mon Sep 17 00:00:00 2001 From: Thomas Pedersen Date: Thu, 3 Nov 2011 21:11:11 -0700 Subject: [PATCH] mac80211: QoS multicast frames have No Ack policy Previously QoS multicast frames had the Normal Acknowledgment QoS control bits set. This would cause broadcast frames to be discarded by peers with which we have a BA session, since their sequence number would fall outside the allowed range. Set No Ack QoS control bits on multicast QoS frames and filter these in de-aggregation code.
