3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dmitry Petukhov <[email protected]> [ Upstream commit f34c4a35d87949fbb0e0f31eba3c054e9f8199ba ] 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.
