Commit in fixes tag removed the match_metadata Tx offload.
This patch removes the option to select this offload from testpmd
menu, help text and documentation.
It also modifies the cmd_show_tx_metadata_parsed() function, to
display the value correctly, and the dump_pkt_burst() function to
display the relevant (Tx/Rx) metadata only.

The dynamic mbuf fields were introduced by [1]. The egress metadata is
good candidate to be moved from statically allocated field tx_metadata to
dynamic one. Because mbufs are used in half-duplex fashion only, it is
safe to share this dynamic field with ingress metadata.
The shared dynamic field contains either egress (if application going to
transmit mbuf with tx_burst) or ingress (if mbuf is received with rx_burst)
metadata and 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_TX_DYNF_METADATA/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 accessing the data.
The availability of dynamic mbuf metadata field can be checked with
rte_flow_dynf_metadata_avail() routine.
DEV_TX_OFFLOAD_MATCH_METADATA offload and configuration flag is removed.
The metadata support in PMDs is engaged on dynamic field registration.
Metadata feature is getting complex. We might have some set of actions
and items that might be supported by PMDs in multiple combinations,
the supported values and masks are the subjects to query by perfroming
trials (with rte_flow_validate).

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.

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

In some scenarios, the raw_encap/raw_decap actions could be multiple in
one single flow (e,g. hirepin flow):
... actions raw_decap / raw_encap / raw_decap / raw_encap / ...
This requires the testpmd supports multiple raw_encap/raw_decap data
settings as well.
With the multiple raw_encap/raw_decap settings, the testpmd commands –
set raw_encap / set raw_decap will become:
set raw_encap <index> <item pattern>
set raw_decap <index> <item pattern>
And the actions – raw_encap/raw_decap also could optionally choose which
global raw_encap/raw_decap confs to be used by index:
... actions raw_decap index 1 / raw_encap index 2 / ...
If there is no `index` specified, the default index is 0:
set raw_encap <item pattern>
... actions raw_decap / raw_encap / ...
which will use raw_encap index 0.
In addition to the set raw_encap/raw_decap commands,
show <raw_encap/raw_decap> <index>
show <raw_encap/raw_decap> all
are also introduced into in order to check which index is set and to
what.
