Subject: [dpdk-stable] [PATCH] net/mlx5: fix incorrect pointer operation
Date: Tue,  7 Jan 2020 10:56:31 +0200
Message-ID: <1578387392-114282-1-git-send-email-suanmingm@mellanox.com> (raw)

The meter suffix flow item pointer restore is not correct to minus a
fixed value. It should minus the real offset it increases.

Set the value to the real offset the pointer increases to fix the issue.

Fixes: 9ea9b049a960 ("net/mlx5: split meter flow")
Cc: stable@dpdk.org
