RTE sample action support a list of actions that be defined as below struct=
ure:
struct rte_flow_action_sample {
uint32_t ratio; /**< packets sampled equals to '1/ratio'. */
const struct rte_flow_action *actions;
/**< sub-action list specific for the sampling hit cases. */
};
So the second part meaning that 'encap' with 'port' combination can be in t=
he 'sub-action' list of sample
Or flow actions while user calls rte_flow_create(,, actions[]);
