ip: Path MTU
Type: feature
Support setting the MTU for a peer on an interface. The minimum value of
the path and interface MTU is used at forwarding time.
the path MTU is specified for a given peer, by address and table-ID.
In the forwarding plane the MTU is enfored either:
1 - if the peer is attached, then the MTU is set on the peer's
adjacency
2 - if the peer is not attached, it is remote, then a DPO is added to
the peer's FIB entry to perform the necessary fragmentation.
