* **Added igb, ixgbe and i40e ethernet driver to support RSS with flow API.**
Rte_flow actually defined to include RSS, but till now, RSS is out of
rte_flow. This patch is to support igb and ixgbe NIC with existing RSS
configuration using rte_flow API.
Added support for igb, ixgbe and i40e NICs with existing RSS configuration
using the ``rte_flow`` API.
* **Add MAC loopback support 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.

* **Added New eventdev Ordered Packet Distribution Library (OPDL) PMD.**
The OPDL (Ordered Packet Distribution Library) eventdev is a specific
implementation of the eventdev API. It is particularly suited to packet
processing workloads that have high throughput and low latency requirements.
All packets follow the same path through the device. The order in which
packets follow is determinted by the order in which queues are set up.
packets follow is determined by the order in which queues are set up.
Events are left on the ring until they are transmitted. As a result packets
do not go out of order.

The Rawdev library provides support for integrating any generic device type with
the DPDK framework. Generic devices are those which do not have a pre-defined
type within DPDK, for example, ethernet, crypto, event etc.
A set of northbound APIs have been defined which encompass a generic set of
operations by allowing applications to interact with device using opaque
structures/buffers. Also, southbound APIs provide APIs for integrating device
structures/buffers. Also, southbound APIs provide a means of integrating devices
either as as part of a physical bus (PCI, FSLMC etc) or through ``vdev``.
