From a32452366b7250c42e96a18ffc3ad8db9e0ca3c2 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Wed, 16 Apr 2014 09:01:03 +0200 Subject: vti4: Don't count header length twice. We currently count the size of LL_MAX_HEADER and struct iphdr twice for vti4 devices, this leads to a wrong device mtu. The size of LL_MAX_HEADER and struct iphdr is already counted in ip_tunnel_bind_dev(), so don't do it again in vti_tunnel_init().
