v3 changes:
 * use i40e_fw_version_get(struct rte_eth_dev *dev, u32 *fw_major,
   u32 *fw_minor, __rte_unused u32 *fw_patch, u32 *etrack_id)
   instead of i40e_fw_version_get(struct rte_eth_dev *dev,
   char *fw_version, int fw_length). Add statusment in
   /doc/guides/nics/features/i40e.ini.
v5 changes:
 * use the function interface in patch v2.
