Existing API supports counter action to count traffic of a single flow. The user can share the count action among different flows using the shared flag and the same counter ID in the count action configuration. Recent patch [1] introduced the indirect action API. Using this API, an action can be created as indirect, unattached to any flow rule. Multiple flows can then be created using the same indirect action. The new API also supports query operation of an indirect action. The new API is more efficient because the driver gets it's own handler for the count action instead of managing a mapping between the user ID to the driver handle. Support create, query and destroy indirect action operations for flow count action. Application will use the indirect action query operation to query this count action. In the meantime the old sharing mechanism (with the sharing flag) continues to be supported, and the user can choose the way he wants to share the counter. The new indirect action API is only supported in DevX, so sharing counter action in Verbs can only be done through the old mechanism.
