+Subject: [PATCH 1/3] Implement APuP Access Point Micro Peering
+
+Access Point Micro Peering is a simpler and hopefully more useful successor to
+Ad Hoc, Wireless Distribution System, 802.11s mesh mode, Multi-AP and EasyMesh.
+When enabled almost plain APs communicate between them via 4-address mode,
+like in WDS but all of them are AP, so they can eventually communicate also
with
+plain stations and more AP nodes in sight, without more trickery.
+APuP has low hardware requirements, just AP mode support + 4-address mode, and
+no more unnecessary complications, like hardcoded bridging or routing algorithm
+in WiFi stack.
+For each AP in sight an interface is created, and then it can be used as
+convenient in each case, bridging, routing etc.
+Those interfaces could be simply bridged in a trivial topology (which happens
+automatically if wds_bridge is not an empty string), or feeded to a
+routing daemon.
