To support the meter policy for yellow action, the prerequisite is
that the hardware needs to support the EBS, as defined in the
RFC2697.
https://datatracker.ietf.org/doc/html/rfc2697
Then some of the packets can be marked as yellow if the tokens of C
bucket is not enough but enough in E bucket. The color could be used
for the further steering of the packets.
In the current implementation EBS and overflow were ignored when
creating a meter profile. With this commit, if EBS is set by the
application, the generation of yellow color will be enabled in the
hardware for flow rules steering of packets.

When creating a flow with this action context for CT, it needs to be
translated in 2 levels.
First, retrieve from action context to rte_flow action.
Second, translate it to the corresponding DR action with traffic
direction that was specified when creating or updating via
rte_flow_action_handle* API.
Before using the DR action in a flow, the CT context should be
available to use in the hardware. A synchronization is done before
inserting the flow rule with CT action to check the HW availability
of this CT context.
In order to release the DR actions and reuse the context of a CT,
the reference count should also be handled in the flow rule
destroying.
The CT index will be recorded in the rte_flow by reusing the ASO age
index to save memory, since only one ASO action is supported in one
flow rule currently. The action context type should also be saved
for CT. When destroying a flow rule, if the context type is CT and
the index is valid (non-zero), the release process should be
handled. By default, the handling will fall back to try to release
the ASO age if any.

After the connection tracking context is created and being used by
the flows, the context will be updated by the HW automatically after
a packet passed the CT validation. E.g., the ACK, SEQ, window and
state of CT can be updated with both direction traffic.
In order to query the updated contents of this context, a WQE should
be posted to the SQ with a return buffer. The data will be filled
into the buffer. And the profile will be filled with specific value.
During the execution of query command, the context may be updated.
The result of the query command may not be the latest one.

When freeing the IB shared context during stopping a device, the
ASO connection tracking management structure should also be cleaned
up.
All the DR actions created should be destroyed. The structures need
to be freed and ASO CT QP should be released. In the meanwhile, the
allocated and registered memory region for query should also be
deregistered and then freed.

After the connection tracking object bulk is allocated, all the
objects' contents are filled with zero by default. Every
new-allocated object must be modified via WQE operation before it is
used.
In order to reduce the latency for the flow creation, an asynchronous
way is used instead of busy waiting for the CQE to be generated.

The definitions of ASO connection tracking objects management
structures are added.
Considering performance, the bulk allocation of ASO CT objects
should be used. The maximal value per bulk and the granularity could
be fetched from HCA capabilities 2. Right now, a fixed number of 64
is used for each bulk for a better management purpose.
The ASO QP for CT is initialized, the SQ will be used for both
modify and query command.

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.
Implement the next policy operations:
validate:
The driver doesn't support to configure actions in the flow
after the meter action except one case when the meter policy
is configured to do nothing in GREEN\YELLOW and only DROP action
in RED, this special policy is called non-terminated policy
and is handed as a singleton object internally.
For all the terminated policies, the next actions are supported:
GREEN - QUEUE, RSS, PORT_ID, JUMP, DROP, MARK and SET_TAG.
YELLOW - not supported at all -> must be empty.
RED - must include DROP action.
Hence, in ingress case, for example,
QUEUE\RSS\JUMP must be configured as last action for GREEN color.
All the above limitations will be validated.
create:
Validate the policy configuration.
Prepare the related tables and actions.
destroy:
Release the created policy resources.

Currently, the flow meter policy does not support multiple actions
per color; also the allowed action types per color are very limited.
In addition, the policy cannot be pre-defined.
Due to the growing in flow actions offload abilities there is a potential
for the user to use variety of actions per color differently.
This new meter policy API comes to allow this potential in the most ethdev
common way using rte_flow action definition.
A list of rte_flow actions will be provided by the user per color
in order to create a meter policy.
In addition, the API forces to pre-define the policy before
the meters creation in order to allow sharing of single policy
with multiple meters efficiently.
meter_policy_id is added into struct rte_mtr_params.
So that it can get the policy during the meters creation.
Allow coloring the packet using a new rte_flow_action_color
as could be done by the old policy API.
Add two common policy template as macros in the head file.
The next API function were added:
- rte_mtr_meter_policy_add
- rte_mtr_meter_policy_delete
- rte_mtr_meter_policy_update
- rte_mtr_meter_policy_validate
The next struct was changed:
- rte_mtr_params
- rte_mtr_capabilities
The next API was deleted:
- rte_mtr_policer_actions_update
To support this API the following app were changed:
app/test-flow-perf: clean meter policer
app/testpmd: clean meter policer
To support this API the following drivers were changed:
net/softnic: support meter policy API
1. Cleans meter rte_mtr_policer_action.
2. Supports policy API to get color action as policer action did.
The color action will be mapped into rte_table_action_policer.
net/mlx5: clean meter creation management
Cleans and breaks part of the current meter management
in order to allow better design with policy API.
