[PATCH v4 1/3] ethdev: add enum type for loop on Rx/Tx offloads

[Wei Dai <wei.dai@intel.com>]

This patch adds enum rte_eth_rx_offload_type and
enum rte_eth_tx_offload_type. For a loop on all
Rx offloads, it is convenient to begin with the
first enum member ETH_RX_OFFLOAD_FIRST_FEATURE
and to end at ETH_RX_OFFLOAD_TOTAL_NUM.
A loop on all Tx offloads can begin with
ETH_TX_OFFLOAD_FIRST_FEATURE and end at
ETH_TX_OFFLOAD_TOTAL_NUM.
