vti: Add pmtu handling to vti_xmit.
We currently rely on the PMTU discovery of xfrm. However if a packet is locally sent, the PMTU mechanism of xfrm tries to do local socket notification what might not work for applications like ping that don't check for this. So add pmtu handling to vti_xmit to report MTU changes immediately. Reported-by: Mark McKinstry <Mark.McKinstry@alliedtelesis.co.nz> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
