Message-Id: <1519165995-50854-5-git-send-email-yuvalm@mellanox.com>
Date: Wed, 21 Feb 2018 00:33:08 +0200
From: Yuval Mintz <yuvalm@...lanox.com>

Subject: [RFC net-next 04/11] mroute*: Make mr_table a common struct
Following previous changes to ip6mr, mr_table and mr6_table are
basically the same [up to mr6_table having additional '6' suffixes to
its variable names].
Move the common structure definition into a common header; This
requires renaming all references in ip6mr to variables that had the
distinct suffix.
