Subject: [dpdk-dev] [PATCH v5 8/9] net/mlx5: improve xstats of bonding port
Date: Sun, 28 Mar 2021 13:48:14 +0000
Message-ID: <1616939297-15627-9-git-send-email-xuemingl@nvidia.com> (raw)
In-Reply-To: <1616939297-15627-1-git-send-email-xuemingl@nvidia.com>
In-Reply-To: <1608304614-13908-2-git-send-email-xuemingl@nvidia.com>

In case of kernel bonding device, counter was read from first bonding PF
member.

This patch reads all member PFs and sums to get bond xstats.
