[PATCH net-next 0/3] l2tp: sanitise MTU handling on sessions

2018-08-03 Thread Guillaume Nault
Most of the code handling sessions' MTU has no effect. The ->mtu field in struct l2tp_session might be used at session creation time, but neither PPP nor Ethernet pseudo-wires take updates into account. L2TP sessions don't have a concept of MTU, which is the reason why ->mtu is mostly ignored.
