app/testpmd: dump TCI when asking for VLAN insertion

I got some report for users that VLAN insertion was not working as the
only thing they could see in verbose mode was a 0x0800 ethertype even
though the RTE_MBUF_F_TX_VLAN flag was shown.

Dump the VLAN TCI from mbuf metadata when VLAN insertion is requested.
This should enhance the situation.

ethdev: advertise flow restore in mbuf

As reported by Ilya [1], unconditionally calling
rte_flow_get_restore_info() impacts an application performance for drivers
that do not provide this ops.
It could also impact processing of packets that require no call to
rte_flow_get_restore_info() at all.

Register a dynamic mbuf flag when an application negotiates tunnel
metadata delivery (calling rte_eth_rx_metadata_negotiate() with
RTE_ETH_RX_METADATA_TUNNEL_ID).

Drivers then advertise that metadata can be extracted by setting this
dynamic flag in each mbuf.

The application then calls rte_flow_get_restore_info() only when required.

app/testpmd: fix flow transfer proxy port handling

The current approach detects the proxy port on each port (re-)plug and
may spam the log with error messages if the PMD does not support flows.
As testpmd is a debug tool, it must not do such implicit port handling.
Instead, the new API should be called only when the user requests that.

Revoke the existing code. Implement an explicit command-line primitive
to let the user find the proxy port themselves. Provide relevant hints.

app/testpmd: add commands for tunnel offload

Tunnel Offload API provides hardware independent, unified model
to offload tunneled traffic. Key model elements are:
- apply matches to both outer and inner packet headers
during entire offload procedure;
- restore outer header of partially offloaded packet;
- model is implemented as a set of helper functions.

Implementation details:

* Create application tunnel:
flow tunnel create <port> type <tunnel type>
On success, the command creates application tunnel object and returns
the tunnel descriptor. Tunnel descriptor is used in subsequent flow
creation commands to reference the tunnel.

* Create tunnel steering flow rule:
tunnel_set <tunnel descriptor> parameter used with steering rule
template.

* Create tunnel matching flow rule:
tunnel_match <tunnel descriptor> used with matching rule template.

* If tunnel steering rule was offloaded, outer header of a partially
offloaded packet is restored after miss.

Example:
test packet=

app/testpmd: support mbuf dynamic flag

DPDK now supports registration of dynamic flags (dynf) to the mbuf.
dynf can be given any name, and can be used with a supporting PMD or
supporting application.

Due to the generic concept of the dynf, it is impossible and
meaningless, to define register set/get function for each flag.
This commit introduce a generic way to register and set/clear such
flags.

The basic syntax:
port config <port id> dynf <name> <set|clear>

The first step the new flag is registered. Regardless if the action is
set or clear.
There is no way to unregister the flag, after registering it.

The second step, if the action is set then we set the requested flag.
If this is the first flag that is enabled we also register a call back
for the Tx. In this call back we set the flag.
If the action is clear the requested flag is cleared, and if there
are no more flags that are set, the call back is removed.

The reason that the set is only applied in Tx is that in case of Rx
it is assumed that the value comes from the PMD.

If log is enabled the name of the flag, and value will be printed
in the packet info.
In order for the log to work correctly the registration of the flag
must be done before setting verbose.

ethdev: move egress metadata to dynamic field

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).

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.
