Need sysadmin to set MAC address manually for VF

[ChenjieXu]

Brief Description
-----------------
After allocating VFs by system command, sysadmin still needs to set MAC address for each VF by ip link command. If a lot of VFs are allocated such as 64 VFs, it will be tedious to set the MAC address or sysadmin needs to write a script. It will be better that StarlingX can set the MAC address automatically for the VFs.

Steps to Reproduce
------------------
1.Set up StarlingX AIO Simplex
2. system host-lock controller-0
   system host-if-modify -m 1500 -n sriov1 -d datanet1 -c pci-sriov -N 64 --vf-driver=vfio controller-0 ens801f1
   system host-unlock controller-0
   ip link show ens801f1
3. sysadmin needs to use ip link command to set the MAC address
   sudo ip link set ens801f1 vf 0 mac 9e:fd:e6:dd:c1:01
   sudo ip link set ens801f1 vf 1 mac 9e:fd:e6:dd:c1:02
   ……
   sudo ip link set ens801f1 vf 63 mac 9e:fd:e6:dd:c1:64

Expected Behavior
------------------
It will be better that StarlingX set the MAC address automatically.

Actual Behavior
----------------
sysadmin needs to set the MAC address manually.

By default, the mac address is first set to 0, but it will be assigned automatically by the system once the VF is instantiated.

Hi Ghada/Steven,

The user also needs to know the MAC address of the allocated VF. For now, user can get the PCI addresses of the allocated VFs by env as following:

[root@testpmd /]# env
```
PCIDEVICE_INTEL_COM_PCI_SRIOV_NET_PHYSNET1=0000:41:02.0,0000:41:02.1
```

Maybe StarlingX can also put the MAC address of the allocated VF in the env.
