From 411d6ed93a5d0601980d3e5ce75de07c98e3a7de Mon Sep 17 00:00:00 2001 From: Marek Lindner Date: Wed, 8 May 2013 13:31:59 +0800 Subject: batman-adv: consider network coding overhead when calculating required mtu The module prints a warning when the MTU on the hard interface is too small to transfer payload traffic without fragmentation. The required MTU is calculated based on the encapsulation header size. If network coding is compild into the module its header size is taken into account as well.
