From 40041ecea334c0106c0e840a32aef92b0cbb004b Mon Sep 17 00:00:00 2001

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.
