* **Add MAC loopback support for i40e.** Also enabled queue region configuration using the ``rte_flow`` API for i40e.
Add MAC loopback support for i40e in order to support test task asked by
users. According to the device configuration, it will setup TX->RX loopback
link or not.
* **Add the support of run time determination of number of queues per i40e VF**
The number of queue per VF is determined by its host PF. If the PCI address
of an i40e PF is aaaa:bb.cc, the number of queues per VF can be configured
with EAL parameter like -w aaaa:bb.cc,queue-num-per-vf=n. The value n can be
1, 2, 4, 8 or 16. If no such parameter is configured, the number of queues
per VF is 4 by default.
