I have a feature request -- has there been any consideration to getting batman-adv to fragment ethernet frames, so as to get a 1500 byte MTU batman-adv network running on top of a 1500 byte MTU ethernet network? This would be a useful feature for people trying to reuse whatever random ethernet networks happen to be nearby to extend their mesh, while not requiring the mesh users to all configure a lower MTU. And the support you've announced for combining small ethernet frames into larger batman-adv frames means that the overhead might not be too bad.
The B.A.T.M.A.N. team is pleased to announce the availability of the second
batman-adv release which brings major improvements, new features, changes
along the way and a series of bugfixes.
