Subject: [dpdk-dev] [PATCH v2 4/6] net/mlx5: remove verbs fork check
Date: Fri, 15 Sep 2017 23:59:58 +0800	[thread overview]
Message-ID: <1505491200-72127-4-git-send-email-xuemingl@mellanox.com> (raw)
In-Reply-To: <1505491200-72127-1-git-send-email-xuemingl@mellanox.com>

Verbs API prohibited resources inheritance by default, this further
disabled PMD forked secondary process that replis on memory inherited
from parent process.

This patch removes verbs fork check to enable DPDK forked process.
