Currenlty the encap/decap actions only support encapsulation
of VXLAN and NVGRE L2 packets (L2 encapsulation is where
the inner packet has a valid Ethernet header, while L3 encapsulation
is where the inner packet doesn't have the Ethernet header).
In addtion the parameter to to the encap action is a list of rte items,
this results in 2 extra translation, between the application to the
actioni and from the action to the NIC. This results in negative impact
on the insertion performance.
Looking forward there are going to be a need to support many more tunnel
encapsulations. For example MPLSoGRE, MPLSoUDP.
Adding the new encapsulation will result in duplication of code.
For example the code for handling NVGRE and VXLAN are exactly the same,
and each new tunnel will have the same exact structure.
This patch introduce a raw encapsulation that can support L2 tunnel types
and L3 tunnel types. In addtion the new
encapsulations commands are using raw buffer inorder to save the
converstion time, both for the application and the PMD.
In order to encapsulate L3 tunnel type there is a need to use both
actions in the same rule: The decap to remove the L2 of the original
packet, and then encap command to encapsulate the packet with the
tunnel.
For decap L3 there is also a need to use both commands in the same flow
first the decap command to remove the outer tunnel header and then encap
to add the L2 header.

As described in [1], a new rte_flow item is added to support metadata
to use as flow rule match pattern.
The metadata is an opaque item, fully controlled by the application.
The use of metadata is relevant for egress rules only.
It can be set in the flow rule using the RTE_FLOW_ITEM_META.
An additional member 'tx_metadata' is added in union with existing member
'hash' of struct 'rte_mbuf', located to avoid conflicts with existing
fields. This additional member is used to carry the metadata item.
Application should set the packet metadata in the mbuf dedicated field,
and set the PKT_TX_METADATA flag in the mbuf->ol_flags.
The NIC will use the packet metadata as match criteria for relevant
flow rules.
This patch introduces metadata item type for rte_flow RTE_FLOW_ITEM_META,
along with corresponding struct rte_flow_item_meta and ol_flag
PKT_TX_METADATA.

This action is useful for offloading loopback mode, where the hardware
will swap source and destination MAC addresses in the outermost Ethernet
header before looping back the packet. This action can be used in
conjunction with other rewrite actions to achieve MAC layer transparent
NAT where the MAC addresses are swapped before either the source or
destination MAC address is rewritten and NAT is performed.
Must be used with a valid RTE_FLOW_ITEM_TYPE_ETH flow pattern item.
Otherwise, RTE_FLOW_ERROR_TYPE_ACTION error should be returned by the
PMDs.

rte_flow_copy() is bound to duplicate flow rule descriptions
(attributes, pattern and list of actions, all at once), however
applications sometimes need more flexibility, for instance the ability
to duplicate only one of the underlying objects (a single pattern item
or action) or retrieve other properties such as their names.
Instead of adding dedicated functions to handle each possible use case,
this patch introduces rte_flow_conv(), which supports any number of
object conversion operations in an extensible manner.
This patch re-implements rte_flow_copy() as a wrapper to
rte_flow_conv().

Library folder name and output library name are same except a few flaws
including librte_ether.
This library is network device abstraction layer, the name "ethdev" fits
better than "ether", and library & header files already named as ethdev.
Also there is a rte_ether.h in the net library which can cause confusion.
