Subject: [dpdk-dev] [PATCH v2 13/17] net/mlx5: add scheduling support to send routine template
Date: Wed, 15 Jul 2020 06:21:50 +0000
Message-ID: <1594794114-16313-14-git-send-email-viacheslavo@mellanox.com> (raw)
In-Reply-To: <1594794114-16313-1-git-send-email-viacheslavo@mellanox.com>

This patch adds send scheduling on timestamps into tx_burst
routine template. The feature is controlled by static configuration
flag, the actual routines supporting the new feature are generated
over this updated template.
