c7870bfe09 ethdev: move RSS expansion code to mlx5 driver
Patch [1] added support for RSS flow expansion.
It was added in ethdev for public use, but until now it is used only
by MLX5 PMD.
To allow local changes in this code, this patch removes it from ethdev
and moves it to MLX5 PMD file.

7f6a3168ed ethdev: fix RSS flow expansion in case of mismatch
Function rte_flow_expand_rss() is used to expand a flow rule with
partial pattern into several rules, to ensure all relevant packets
are matched.
It uses utility function rte_flow_expand_rss_item_complete(), to check
if the last valid item in the flow rule pattern needs to be completed.
For example the pattern "eth / ipv4 proto is 17 / end" will be completed
with a "udp" item.
This function returns "void" item in two cases:
1) The last item has empty spec, for example "eth / ipv4 / end".
2) The last itme has spec that can't be expanded for RSS.
   For example the pattern "eth / ipv4 proto is 47 / end" ends with IPv4
   item that has next protocol GRE.

In both cases the flow rule may be expanded, but in the second case such
expansion may create rules with invalid pattern.
For example "eth / ipv4 proto is 47 / udp / end".
In such a case the flow rule should not be expanded.

This patch updates function rte_flow_expand_rss_item_complete().
Return value RTE_FLOW_ITEM_TYPE_END is used to indicate the flow rule
should not be expanded.
In such a case, rte_flow_expand_rss() will return with the original flow
rule only, without any expansion.

d164c609e7 ethdev: add eCPRI key fields to flow API
Add a new item "rte_flow_item_ecpri" in order to match eCRPI header.

eCPRI is a packet based protocol used in the fronthaul interface of
5G networks. Header format definition could be found in the
specification via the link below:
https://www.gigalight.com/downloads/standards/ecpri-specification.pdf

eCPRI message can be over Ethernet layer (.1Q supported also) or over
UDP layer. Message header formats are the same in these two variants.

44bf3c796b ethdev: support flow aging
One of the reasons to destroy a flow is the fact that no packet matches
the flow for "timeout" time.
For example, when TCP\UDP sessions are suddenly closed.

Currently, there is not any DPDK mechanism for flow aging and the
applications use their own ways to detect and destroy aged-out flows.

The flow aging implementation need include:
- A new rte_flow action: RTE_FLOW_ACTION_TYPE_AGE to set the timeout and
  the application flow context for each flow.
- A new ethdev event: RTE_ETH_EVENT_FLOW_AGED for the driver to report
  that there are new aged-out flows.
- A new rte_flow API: rte_flow_get_aged_flows to get the aged-out flows
  contexts from the port.
- Support input flow aging command line in Testpmd.

The new event type addition in the enum is flagged as an ABI breakage,
so an ignore rule is added for these reasons:
- It is not changing value of existing types (except MAX)
- The new value is not used by existing API if the event is not
  registered
In general, it is safe adding new ethdev event types at the end of the
enum, because of event callback registration mechanism.

64edb05e29 ethdev: fix item expansion for RSS flow
When the last item in flow pattern includes "next protocol" field which
is relevant for RSS flow expansion, a new item is added to the pattern
according to the "next protocol" field. This field is called missed
field.

The missed field wrongly was not initialized what caused to some of the
flow item fields to contain garbage values.

As a result, the PMDs internal flow engine may crash.

For example, the spec value may include garbage pointer and to cause
crash.

Initialize the missed field with zeroes.

eccc5d3237 ethdev: fix last item detection on RSS flow expand
There is a rte_flow API which expands a RSS flow pattern to multiple
patterns according to the RSS hash types in the RSS action
configuration.

As part of the expansion, detection of the last item of the flow uses
the "next proto" field of the last configured item in the pattern list.
Wrongly, the mask of this field was not considered in order to validate
the field.

Ignore "next proto" fields when their corresponded masks invalidate them.

fc2dd8dd49 ethdev: fix expand RSS flows
rte_flow_expand_rss expands rte_flow item list based on the RSS
types. In another word, some additional rules are added if the user
specified items are not complete enough according to the RSS type,
for example:

  ... pattern eth / end actions rss type tcp end ...

User only provides item eth but want to do RSS on tcp traffic.
The pattern is not complete enough to filter TCP traffic only.
This will be a problem for some HWs.
So some PMDs use rte_flow_expand_rss to expand above user provided
flow to:

  ... pattern eth / end actions rss types tcp
  ... pattern eth / ipv4 / tcp / end actions rss types tcp ...
  ... pattern eth / ipv6 / tcp / end actions rss types tcp ...

in order to filter TCP traffic only and do RSS correctly.

However the current expansion cannot handle pattern as below, which
provides ethertype or ip next proto instead of providing an item:

  ... pattern eth type is 0x86DD / end actions rss types tcp ...

rte_flow_expand_rss will expand above flow to:

  ... pattern eth type is 0x86DD / ipv4 / tcp end ...

which has conflicting values: 0x86DD vs. ipv4 and some HWs will refuse
to create flow.

This patch will fix above by checking the last item's spec and to
expand RSS flows correctly.

Currently only support to complete item list based on ether type or ip
next proto.

e02ecc1324 ethdev: extend flow metadata
Currently, metadata can be set on egress path via mbuf tx_metadata field
with PKT_TX_METADATA flag and RTE_FLOW_ITEM_TYPE_META matches metadata.

This patch extends the metadata feature usability.

1) RTE_FLOW_ACTION_TYPE_SET_META

When supporting multiple tables, Tx metadata can also be set by a rule and
matched by another rule. This new action allows metadata to be set as a
result of flow match.

2) Metadata on ingress

There's also need to support metadata on ingress. Metadata can be set by
SET_META action and matched by META item like Tx. The final value set by
the action will be delivered to application via metadata dynamic field of
mbuf which can be accessed by RTE_FLOW_DYNF_METADATA() macro or with
rte_flow_dynf_metadata_set() and rte_flow_dynf_metadata_get() helper
routines. PKT_RX_DYNF_METADATA flag will be set along with the data.

The mbuf dynamic field must be registered by calling
rte_flow_dynf_metadata_register() prior to use SET_META action.

The availability of dynamic mbuf metadata field can be checked
with rte_flow_dynf_metadata_avail() routine.

If application is going to engage the metadata feature it registers
the metadata  dynamic fields, then PMD checks the metadata field
availability and handles the appropriate fields in datapath.

For loopback/hairpin packet, metadata set on Rx/Tx may or may not be
propagated to the other path depending on hardware capability.

MARK and METADATA look similar and might operate in similar way,
but not interacting.

Initially, there were proposed two metadata related actions:

- RTE_FLOW_ACTION_TYPE_FLAG
- RTE_FLOW_ACTION_TYPE_MARK

These actions set the special flag in the packet metadata, MARK action
stores some specified value in the metadata storage, and, on the packet
receiving PMD puts the flag and value to the mbuf and applications can
see the packet was threated inside flow engine according to the appropriate
RTE flow(s). MARK and FLAG are like some kind of gateway to transfer some
per-packet information from the flow engine to the application via
receiving datapath. Also, there is the item of type RTE_FLOW_ITEM_TYPE_MARK
provided. It allows us to extend the flow match pattern with the capability
to match the metadata values set by MARK/FLAG actions on other flows.

From the datapath point of view, the MARK and FLAG are related to the
receiving side only. It would useful to have the same gateway on the
transmitting side and there was the feature of type RTE_FLOW_ITEM_TYPE_META
was proposed. The application can fill the field in mbuf and this value
will be transferred to some field in the packet metadata inside the flow
engine. It did not matter whether these metadata fields are shared because
of MARK and META items belonged to different domains (receiving and
transmitting) and could be vendor-specific.

So far, so good, DPDK proposes some entities to control metadata inside
the flow engine and gateways to exchange these values on a per-packet basis
via datapaths.

As we can see, the MARK and META means are not symmetric, there is absent
action which would allow us to set META value on the transmitting path.
So, the action of type:

- RTE_FLOW_ACTION_TYPE_SET_META was proposed.

The next, applications raise the new requirements for packet metadata.
The flow ngines are getting more complex, internal switches are introduced,
multiple ports might be supported within the same flow engine namespace.
From the DPDK points of view, it means the packets might be sent on one
eth_dev port and received on the other one, and the packet path inside
the flow engine entirely belongs to the same hardware device. The simplest
example is SR-IOV with PF, VFs and the representors. And there is a
brilliant opportunity to provide some out-of-band channel to transfer
some extra data from one port to another one, besides the packet data
itself. And applications would like to use this opportunity.

It is supposed for application to use trials (with rte_flow_validate)
to detect which metadata features (FLAG, MARK, META) actually supported
by PMD and underlying hardware. It might depend on PMD configuration,
system software, hardware settings, etc., and should be detected
in run time.

9a2f44c762 ethdev: add flow tag
A tag is a transient data which can be used during flow match. This can be
used to store match result from a previous table so that the same pattern
need not be matched again on the next table. Even if outer header is
decapsulated on the previous match, the match result can be kept.

Some device expose internal registers of its flow processing pipeline and
those registers are quite useful for stateful connection tracking as it
keeps status of flow matching. Multiple tags are supported by specifying
index.

Example testpmd commands are:

  flow create 0 ingress pattern ... / end
    actions set_tag index 2 value 0xaa00bb mask 0xffff00ff /
            set_tag index 3 value 0x123456 mask 0xffffff /
            vxlan_decap / jump group 1 / end

  flow create 0 ingress pattern ... / end
    actions set_tag index 2 value 0xcc00 mask 0xff00 /
            set_tag index 3 value 0x123456 mask 0xffffff /
            vxlan_decap / jump group 1 / end

  flow create 0 ingress group 1
    pattern tag index is 2 value spec 0xaa00bb value mask 0xffff00ff /
            eth ... / end
    actions ... jump group 2 / end

  flow create 0 ingress group 1
    pattern tag index is 2 value spec 0xcc00 value mask 0xff00 /
            tag index is 3 value spec 0x123456 value mask 0xffffff /
            eth ... / end
    actions ... / end

  flow create 0 ingress group 2
    pattern tag index is 3 value spec 0x123456 value mask 0xffffff /
            eth ... / end
    actions ... / end

7307cf6333 ethdev: add raw encapsulation action
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.

839b20be0e ethdev: support metadata as flow rule criteria
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.

Otherwise, RTE_FLOW_ERROR_TYPE_ACTION error should be returned by the
PMDs.

c2beb1d469 ethdev: add missing items/actions to flow object converter
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.

063911ee1d ethdev: add flow API object converter
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().

a3783ebf7b ethdev: fix flow expansion matching types
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.

4ed05fcd44 ethdev: add flow API to expand RSS flows
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.

a68e95facc ethdev: fix shallow copy of flow API RAW item
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.

01eb53eefe ethdev: rename folder to library name
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.
