Hi Shao,
	Thanks for your reply.

	I try to keep this PF part support to recv hinic VF PMD driver in DPDK
	upstream.
	the command comes from here,
	https://github.com/DPDK/dpdk/blob/main/drivers/net/hinic/base/hinic_pmd_niccfg.c

	send by the DPDK-hinic function 'l2nic_msg_to_mgmt_sync' when
	'hinic_func_type(hwdev) == TYPE_VF'.

	for the test, the DPDK part is tested, I also test this part in SP582 NIC

Thanks.
Cai
