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.

Several pattern items and actions were never handled by rte_flow_copy()
because their descriptions were missing. rte_flow_conv() inherited this
deficiency.
This patch adds them and reorders others to match rte_flow.h. It doesn't
pose as a fix because so far no one has complained about it and
rte_flow_conv() would have to be backported as well: this function is
the only sane approach to handle VXLAN and NVGRE encap definitions.
As a matter of fact, it's the last missing piece to finally allow
testpmd users to request the creation of VXLAN/NVGRE encap/decap flow
rules without getting rejected outright.

This provides a means for applications to retrieve the name of flow

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().

Node RSS types are generally covering more RSS kind than the user is
requesting, it should accept to expand even if only a single bit is
remains after masking. Setting the correct RSS kind for the rule
remains the driver job.

Introduce an helper for PMD to expand easily flows items list with RSS
action into multiple flow items lists with priority information.
For instance a user items list being "eth / end" with rss action types
"ipv4-udp ipv6-udp end" needs to be expanded into three items lists:
- eth
- eth / ipv4 / udp
- eth / ipv6 / udp
to match the user request. Some drivers are unable to reach such
request without this expansion, this API is there to help those.
Only PMD should use such API for their internal cooking, the application
will still handle a single flow.

COUNT action has been modified and has several fields not addressable
though testpmd. In addition, as those fields are not definable testpmd
is providing an empty configuration which is undefined.

Like original commit mentioned below, this fix synchronizes flow rule copy
function with testpmd's own implementation following "app/testpmd: fix copy
of raw flow item (revisited)".
It addresses a crash that occurs when feeding a RAW pattern item to
rte_flow_copy(). Besides external applications, two PMDs (bonding and
failsafe) rely on this function internally.
Note the scope of this patch is limited to the RAW pattern item and has no
impact on all others.

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.
