MTU: Software interface / Per-protocol MTU support
This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set. Currently only IP4, IP6 are enabled in adjacency / rewrite code. Documentation in src/vnet/MTU.md Change-Id: Iee2fd6f0bbc8210748dd8e073ab9fab87d323690 Signed-off-by: Ole Troan <ot@cisco.com>
