[dpdk-dev] [PATCH v6 0/4] net/mlx5: support meter policy operations

[Li Zhang]

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
