From d723161e038d00e59766aa67a6a0dcc350227e4b Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Thu, 7 Jun 2018 10:17:57 +0200 Subject: 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.
