1. Set MAC address after renaming the interface …

   Setting the MAC address at the end of SetupVF reduces
   the chances of race conditions with tools that set MAC
   address asynchronously (i.e. iavf).
   
   This commit solve an issue with i40e driver where calling
   `SetVFEffectiveMAC` after `SetVFHardwareMAC` may produce
   a VF with no connectivity even if the last configuration step
   didn't produce any error:
   
   ```
   + ip link set dev ens1f0 vf 0 mac 20:04:0f:f1:88:A1   # No error
   + ip link set dev temp_71 address 20:04:0f:f1:88:A1   # Transient error
   RTNETLINK answers: Resource temporarily unavailable
   + ip link set dev temp_71 address 20:04:0f:f1:88:A1   # No error
   ```
   
   Note: this seems to be a kernel driver regression introduced near
   torvalds/linux@c34743d
