Subject: fix two vf virtual machine has same mac address
through 82599,hns3 physical network cart vf two virtual machine,
two virtual machine have the same mac address.

MACAddressPolicy=
The policy by which the MAC address should be set. The available
policies are:

persistent
If the hardware has a persistent MAC address, as most hardware should,
and if it is used by the kernel, nothing is done. Otherwise, a new MAC
address is generated which is guaranteed to be the same on every boot
for the given machine and the given device, but which is otherwise random.
This feature depends on ID_NET_NAME_* properties to exist for the link.
On hardware where these properties are not set, the generation of a
persistent MAC address will fail.

random
If the kernel is using a random MAC address, nothing is done. Otherwise,
a new address is randomly generated each time the device appears,
typically at boot. Either way, the random address will have the "unicast"
and "locally administered" bits set.

none
Keeps the MAC address assigned by the kernel.
