Subject: [dpdk-stable] [PATCH v3 05/14] net/mlx5: fix Rx queue memory allocation return value
Date: Wed, 3 Nov 2021 15:58:29 +0800 [thread overview]
Message-ID: <20211103075838.1486056-6-xuemingl@nvidia.com> (raw)
In-Reply-To: <20211103075838.1486056-1-xuemingl@nvidia.com>
If error happened during Rx queue mbuf allocation, boolean value
returned. From description, return value should be error number.
This patch returns negative error number.
