Subject: [dpdk-stable] [PATCH v2 3/5] regex/mlx5: fix support for group id
Date: Thu,  7 Jan 2021 18:57:09 +0200
Message-ID: <20210107165711.1782-4-orika@nvidia.com> (raw)
In-Reply-To: <20210107165711.1782-1-orika@nvidia.com>

In order to know which groups in the RegEx engine
should be used there is a need to check the req_flags.

This commit adds the missing check.

Cc: stable@dpdk.org

Fixes: 4d4e245ad637 ("regex/mlx5: support enqueue")
