This forward deceleration is not needed.

If 'hns3_dev_infos_get()' sets 'min_mtu' & 'max_mtu' properly, above check will
be done by 'rte_eth_dev_set_mtu()' already.

'RTE_ETHER_MIN_MTU' is default value and can be skipped.

Can you please update .ini file in this patch and mark following features as
supported:
MTU update
FW version
