Subject: [net-next 06/12] net/mlx5e: Add XDP_TX completions statistics
Date: Thu, 28 Jun 2018 14:50:57 -0700 [thread overview]
Message-ID: <20180628215103.9141-7-saeedm@mellanox.com> (raw)
In-Reply-To: <20180628215103.9141-1-saeedm@mellanox.com>
From: Tariq Toukan <tariqt@mellanox.com>
Add per-ring and global ethtool counters for XDP_TX completions.
This helps us monitor and analyze XDP_TX flow performance.
