[dpdk-dev] [PATCH] net/mlx5: support metadata as flow rule criteria
Dekel Peled
dekelp at mellanox.com
Sun Sep 16 15:42:08 CEST 2018
As described in series starting at [1], it adds option to set metadata
value as match pattern when creating a new flow rule.
This patch adds metadata support in mlx5 driver, in several parts:
- Add the setting of metadata value in matcher when creating
a new flow rule.
- Add the passing of metadata value from mbuf to wqe when
indicated by ol_flag, in different burst functions.
- Allow flow rule with attribute egress in specific cases.
This patch must be built together with the files in series [1].
[1] "ethdev: support metadata as flow rule criteria"
