Subject: [dpdk-dev] [PATCH v3] net/mlx5: support e-switch TCP-flags flow filter
Date: Wed, 10 Oct 2018 14:43:38 +0000 [thread overview]
Message-ID: <1539182589-10533-1-git-send-email-motih@mellanox.com> (raw)
In-Reply-To: <1539083548-23240-1-git-send-email-motih@mellanox.com>
This patch adds support for offloading flow rules with TCP-flags
filter to mlx5 eswitch Hardwrae.
With mlx5 it is possible to offload a limited set of flow rules to
the mlxsw (or e-switch) using the DPDK flow commands using the
"transfer" attribute. This set of flow rules also supports filtering
according to the values found in the TCP flags.
This patch implements this offload capability in the mlx5 PMD under
transfer attribute.

v3:
Changes according to review inputs.
* Modified commit header.
* Modified mason build to resemble the changes in Makefile.
* Corrected TCP flags default support mask.
