Message-Id: <1518087422-1513-1-git-send-email-serhe.popovych@gmail.com>
Date: Thu, 8 Feb 2018 12:57:02 +0200
From: Serhey Popovych <serhe.popovych@...il.com>
To: netdev@...r.kernel.org
Subject: [PATCH iproute2-next] ip/tunnel: Minor cleanups
Few minor changes to reduce diffs between ip and ipv6 tunnel code:
1) reduce intendation by one level when adding attributes in gre and
gre6; reorder addattr*() calls to simplify diff
2) reorder local variables definition; change their type (e.g. for
IFLA_LINK) to match ones returned by rta_getattr_*()
3) move "mode" parameter parsing in link_iptnl.c to the similar
position as in link_ip6tnl.c
4) handle "tc" as shortcut for "tclass"/"tos" in link_iptnl.c
5) add whitespace where required
