For batman-adv, because it is a layer 2 protocol, we don't have this system available. We tried different tactics such as using DHCP to tell the clients the MTU they should use, but it turns out that many operating systems completely ignore this. We tried something called TCP MSS clamping, which is a bit of a dirty hack, but that only works for TCP, which is a problem since UDP is widely used for e.g. VOIP, video streaming, gaming, torrenting, etc.

What spoke against using the batman-adv layer2 fragmentation: http://www.open-mesh.org/projects/open-mesh/wiki/2012-09-24-GSoC-2012-Martin... ?
