flow_offload: add ops to tc_action_ops for flow action setup
Add a new ops to tc_action_ops for flow action setup.
Refactor function tc_setup_flow_action to use this new ops.
We make this change to facilitate to add standalone action module.
We will also use this ops to offload action independent of filter
