Date: Thu, 15 May 2014 09:07:52 +0200 From: Steffen Klassert <steffen.klassert@...unet.com> To: David Miller <davem@...emloft.net> CC: Herbert Xu <herbert@...dor.apana.org.au>, Steffen Klassert <steffen.klassert@...unet.com>, <netdev@...r.kernel.org> Subject: [PATCH 2/6] 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().
