> Subject: [PATCH v8 0/4] net/mlx5: support meter policy operations
> 
> MLX5 PMD checks the validation of actions in policy while add a new meter
> policy, if pass the validation, allocates the new policy object from the meter
> policy indexed memory pool.
> 
> It is common to use the same policy for multiple meters.
> MLX5 PMD supports two types of policy: termination policy and no-
> termination policy.
> 
> The termination policy must have a fate action as in the policy actions, it can
> support QUEUE, RSS, PORT_ID, DROP, JUMP, MARK and SET_TAG actions if
> policy color is GREEN, also supports DROP action if policy color is RED.
> 
> The no-termination policy uses policy ID 0 as default policy, it is created
> internal and cannot be changed by API. The default policy red action is drop,
> green action is jump to suffix table.
> Create this policy by policy API with green/yellow no action, red with drop
> action.
> One example in testpmd command:
> add port meter policy 0 g_actions end y_actions end r_actions drop / end
