Hello.
I'm one of the developers of the libre-mesh project [1]. Our aim is to
develop an OpenWRT based solution for quick and easy building free/libre
mesh networks.

Our network architecture is quite different from the common ones, we are
mixing two routing protocols in layer2 and layer3 (batman-adv and bmx6).
You can find more information about it here [2].

Until now we were using Ad-Hoc as link layer, however recently we have
started to consider the idea of using 11s instead. We are not interested
in the routing layer (HWMP) because we need some features provided by
batman-adv, so we disable it by setting the option mesh_forwarding to
false.

I've already performed some tests and the results look quite good. Using
11s instead of ad-hoc bring us some advantages which are:

1. Better support for 11n
2. Better compatibility with drivers
3. You can bridge an 11s interface to another interface if necessary
4. It does NOT try to synchronize the TSF counter of your wifi card
5. You can create up to 8 11s VAP mixed with adhoc, AP, client, etc...
5. Get benefit of a newer protocol design

I would like to know your opinion on this topic. None of us now deeply
how 11s works, so we don't really know if what we are trying to do is a
madness or a good idea. It would be also very interesting for us to know
which options can we tun for getting better profit of using 11s as link
layer.

Thank you for your efforts on developing 11s.

Cheers.
