CONFIG_MAC80211_MESH isn't defined for this package, rendering the patch
useless. Match protecting the access of sta_info.mesh with the very same
define declaring it.
Fixes 45109f69a6 "mac80211: fix compile error when mesh is disabled"

Subject: [PATCH] mac80211: mask nested A-MSDU support for mesh
|
|
|
|
mac80211 incorrectly processes A-MSDUs contained in A-MPDU frames. This
|
|
results in dropped packets and severely impacted throughput.
|
|
|
|
As a workaround, don't indicate support for A-MSDUs contained in
|
|
A-MPDUs. This improves throughput over mesh links by factor 10.
