Are all these headers really used at this stage? Can you please clean them and
add later patches when they are required?

I think no need to call 'rte_eth_copy_pci_info()', it is called by
'rte_eth_dev_pci_generic_probe()' before 'hns3_dev_init()' called.

There is a separate VF driver, is this field still needed?

Init should set 'RTE_ETH_DEV_CLOSE_REMOVE' flag, and '.dev_close' should free
the driver allocated resources, which there is not up until this patch:

 +eth_dev->data->dev_flags |= RTE_ETH_DEV_CLOSE_REMOVE;

I will fix it in patch V2.

hns3 PMD driver includes PF and VF drivers.
In the struct hns3_adapter data, the memeber named is_vf is used to
distinguish PF from VF devices.
