[RFC] Rx adapter create API changes

[Naga Harish K, S V]

Hi all,

The API "rte_event_eth_rx_adapter_create_with_params()" is an extension to rte_event_eth_rx_adapter_create() with additional adapter configuration params structure.
There is no equivalent API existing today for "rte_event_eth_rx_adapter_create_ext()" API. We may need to have one more adapter create API for this.
That makes so many Adapter create APIs and will be confusing for the user.

   I am proposing the following changes to the Rx adapter create APIs which will consolidate the create APIs to 2 in number with all possible combinations.

Current RX Adapter create APIs
Proposed changes
 int rte_event_eth_rx_adapter_create_ext(uint8_t id, uint8_t dev_id,
                    rte_event_eth_rx_adapter_conf_cb conf_cb,
                    void *conf_arg)
 int rte_event_eth_rx_adapter_create_ext(uint8_t id, uint8_t dev_id,
                  rte_event_eth_rx_adapter_conf_cb conf_cb,
                  void *conf_arg,
                  struct rte_event_eth_rx_adapter_params *rxa_params)
 int rte_event_eth_rx_adapter_create(uint8_t id, uint8_t dev_id,
                    struct rte_event_port_conf *port_config)
 int rte_event_eth_rx_adapter_create(uint8_t id, uint8_t dev_id,
                   struct rte_event_port_conf *port_config,
                   struct rte_event_eth_rx_adapter_params *rxa_params)
 int rte_event_eth_rx_adapter_create_with_params(uint8_t id, uint8_t dev_id,
                    struct rte_event_port_conf *port_config,
                    struct rte_event_eth_rx_adapter_params *rxa_params)
                     Will be deprecated.

The applications that are currently using rte_event_eth_rx_adapter_create_ext() or rte_event_eth_rx_adapter_create() APIs for creating Rx adapter can pass NULL argument for the
Newly added argument which will behave same as before.

Let me know your comments for this change.
