From d3c07e5b9939a055fa017f200e535ae947eb22ab Mon Sep 17 00:00:00 2001 From: Yuval Mintz Date: Mon, 26 Mar 2018 15:01:35 +0300 Subject: ip6mr: Add API for default_rule fib Add the ability to discern whether a given FIB rule notification relates to the default rule inserted when registering ip6mr or a different one. Would later be used by drivers wishing to offload ipv6 multicast routes but unable to offload rules other than the default one.
