[Olsr-dev] NL80211 link quality patch and GIT repository

[Henning Rogge]

Can you take a look at this two files?

http://olsr.org/git/?p=dlep_app.git;a=blob;f=src/olsr_layer2.h;h=17afbfec1f9457873016d18fa42a24f93376fe6f;hb=master
http://olsr.org/git/?p=dlep_app.git;a=blob;f=src/olsr_layer2.c;h=feed068def034752476d6a18556493ee56ff1de6;hb=master

That is the "in between datastructure" (or something similar) I
designed for OLSRv2... something between "collects layer-2 data" and
"use layer-2 data to build the metric".

What do you think about the idea?
