[v1] net/mlx5: fix representor item and meter
Checks
Commit Message
When creating flow matching port representor item with meter action, it
will fail due to incorrect parsing the item.
This patch fixes this issue by adding the correct item parse for port
representor in validation.
Fixes: 707d5e7d79 ("net/mlx5: support flow matching on representor ID")
