Subject: [dpdk-dev] [PATCH v3 2/5] net/mlx5: free buffers in bulk on Tx completion
Date: Wed, 5 Jul 2017 11:12:25 -0700 [thread overview]
Message-ID: <8377f0faa69b2b52d3eb0f80a8d73c0fa2069b9e.1499278209.git.yskoh@mellanox.com> (raw)
In-Reply-To: <cover.1499278209.git.yskoh@mellanox.com>
When processing Tx completion, it is more efficient to free buffers in bulk
using rte_mempool_put_bulk() if buffers are from a same mempool.
