From 03ce79e357f3afefe8d1409a98b5ae03c611d611 Mon Sep 17 00:00:00 2001
From: Michal Privoznik <mprivozn@redhat.com>
Date: Fri, 8 Dec 2017 11:18:07 +0100
Subject: [PATCH] tc: util: Don't call NEXT_ARG_FWD() in
__parse_action_control()
Not all callers want parse_action_control*() to advance the
arguments. For instance act_parse_police() does the argument
advancing itself.
Fixes: e67aba559581 ("tc: actions: add helpers to parse and print control actions")
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
(cherry picked from commit 3572e01a090a298e2f4c4f796bad6639b652e031)
