Date: Wed, 9 Apr 2014 02:23:20 +0600 From: Dmitry Petukhov <dmgenp@...il.com> To: netdev@...r.kernel.org Subject: [PATCH net] l2tp: take PMTU from tunnel UDP socket When l2tp driver tries to get PMTU for the tunnel destination, it uses the pointer to struct sock that represents PPPoX socket, while it should use the pointer that represents UDP socket of the tunnel.
