Currently, the defined modes include: 1) NONE: it means no error handling modes are supported by this port. 2) PASSIVE: passive error handling, after the PMD detect that a reset is required, the PMD reports RTE_ETH_EVENT_INTR_RESET event, and application invoke rte_eth_dev_reset() to recover the port.
