c1870f65e6 net/dpaa2: enable optional timestamp in mbuf
This patch enables the population of timestamp field
in mbuf on packet receive.
It may give performance impact on LX2xxx platforms.
So, it has been made optional for Lx2xxx platform.
One shall call, rte_dpaa2_enable_ts() to enable it.

Nothing is required for LS2 and LS1088 platforms.

8877ac688b telemetry: introduce infrastructure
This patch adds the infrastructure and initial code for the telemetry
library.

The telemetry init is registered with eal_init(). We can then check to see
if --telemetry was passed as an eal option. If --telemetry was parsed, then
we call telemetry init at the end of eal init.

Control threads are used to get CPU cycles for telemetry, which are
configured in this patch also.

c9bf83947e eventdev: add eth Tx adapter APIs
The ethernet Tx adapter abstracts the transmit stage of an
event driven packet processing application. The transmit
stage may be implemented with eventdev PMD support or use a
rte_service function implemented in the adapter. These APIs
provide a common configuration and control interface and
an transmit API for the eventdev PMD implementation.

The transmit port is specified using mbuf::port. The transmit
queue is specified using the rte_event_eth_tx_adapter_txq_set()
function.

f0e352ddb0 pipeline: add port in action APIs
This API provides a common set of actions for pipeline input ports to speed
up application development.

Each pipeline input port can be assigned an action handler to be executed
on every input packet during the pipeline execution.

The pipeline library allows the user to define his own input port actions
by providing customized input port action handler. While the user can
still follow this process, this API is intended to provide a quicker
development alternative for a set of predefined actions.

The typical steps to use this API are:
* Define an input port action profile.
* Instantiate the input port action profile to create input port action
  objects.
* Use the input port action to generate the input port action handler
  invoked by the pipeline.
* Use the input port action object to generate the internal data structures
  used by the input port action handler based on given action parameters.

654dd41112 pipeline: add table action APIs
This API provides a common set of actions for pipeline tables to speed up
application development.

Each match-action rule added to a pipeline table has associated data
that stores the action context. This data is input to the table
action handler called for every input packet that hits the rule as
part of the table lookup during the pipeline execution.

The pipeline library allows the user to define his own table
actions by providing customized table action handlers (table
lookup) and complete freedom of setting the rules and their data
(table rule add/delete). While the user can still follow this
process, this API is intended to provide a quicker development
alternative for a set of predefined actions.

The typical steps to use this API are:
* Define a table action profile.
* Instantiate the table action profile to create table action objects.
* Use the table action object to generate the pipeline table action
  handlers (invoked by the pipeline table lookup operation).
* Use the table action object to generate the rule data (for the
  pipeline table rule add operation) based on given action parameters.
* Use the table action object to read action data (e.g. stats counters)
  for any given rule.

6613ffe138 ethdev: add API for traffic metering and policing
This patch introduces new ethdev generic API for Traffic Metering and
Policing (MTR), which is yet another standard RX offload for Ethernet

Similar to rte_flow and rte_tm APIs, the configuration of MTR objects is
done in their own namespace (rte_mtr) within the librte_ether library.

Main features:
1. Traffic metering: determine the color for the current packet (green,
   yellow, red) based on history maintained by the MTR object. Supported
   algorithms: srTCM (RFC 2697), trTCM (RFC 2698 and RFC 4115).
2. Policing (per meter output color actions): re-color the packet (keep
   or change the meter output color) or drop the packet.
3. Statistics
4. Capability API

ec51443cc9 gso: add Generic Segmentation Offload API framework
Generic Segmentation Offload (GSO) is a SW technique to split large
packets into small ones. Akin to TSO, GSO enables applications to
operate on large packets, thus reducing per-packet processing overhead.

To enable more flexibility to applications, DPDK GSO is implemented
as a standalone library. Applications explicitly use the GSO library
to segment packets. To segment a packet requires two steps. The first
is to set proper flags to mbuf->ol_flags, where the flags are the same
as that of TSO. The second is to call the segmentation API,
rte_gso_segment(). This patch introduces the GSO API framework to DPDK.

rte_gso_segment() splits an input packet into small ones in each
invocation. The GSO library refers to these small packets generated
by rte_gso_segment() as GSO segments. Each of the newly-created GSO
segments is organized as a two-segment MBUF, where the first segment is a
standard MBUF, which stores a copy of packet header, and the second is an
indirect MBUF which points to a section of data in the input packet.
rte_gso_segment() reduces the refcnt of the input packet by 1. Therefore,
when all GSO segments are freed, the input packet is freed automatically.
Additionally, since each GSO segment has multiple MBUFs (i.e. 2 MBUFs),
the driver of the interface which the GSO segments are sent to should
support to transmit multi-segment packets.

The GSO framework clears the PKT_TX_TCP_SEG flag for both the input
packet, and all produced GSO segments in the event of success, since
segmentation in hardware is no longer required at that point.

e996506a1c lib/gro: add Generic Receive Offload API framework
Generic Receive Offload (GRO) is a widely used SW-based offloading
technique to reduce per-packet processing overhead. It gains
performance by reassembling small packets into large ones. This
patchset is to support GRO in DPDK. To support GRO, this patch
implements a GRO API framework.

To enable more flexibility to applications, DPDK GRO is implemented as
a user library. Applications explicitly use the GRO library to merge
small packets into large ones. DPDK GRO provides two reassembly modes.
One is called lightweight mode, the other is called heavyweight mode.
If applications want to merge packets in a simple way and the number
of packets is relatively small, they can use the lightweight mode.
If applications need more fine-grained controls, they can choose the
heavyweight mode.

rte_gro_reassemble_burst is the main reassembly API which is used in
lightweight mode and processes N packets at a time. For applications,
performing GRO in lightweight mode is simple. They just need to invoke
rte_gro_reassemble_burst. Applications can get GROed packets as soon as
rte_gro_reassemble_burst returns.

rte_gro_reassemble is the main reassembly API which is used in
heavyweight mode and tries to merge N inputted packets with the packets
in GRO reassembly tables. For applications, performing GRO in heavyweight
mode is relatively complicated. Before performing GRO, applications need
to create a GRO context object, which keeps reassembly tables of
desired GRO types, by rte_gro_ctx_create. Then applications can use
rte_gro_reassemble to merge packets. The GROed packets are in the
reassembly tables of the GRO context object. If applications want to get
them, applications need to manually flush them by flush API.

5cd3cac9ed latency: added new library for latency stats
Add a library designed to calculate latency statistics and report them
to the application when queried. The library measures minimum, average and
maximum latencies, and jitter in nano seconds. The current implementation
supports global latency stats, i.e. per application stats.

349950ddb9 metrics: add information metrics library
This patch adds a new information metrics library. This Metrics
library implements a mechanism by which producers can publish
numeric information for later querying by consumers. Metrics
themselves are statistics that are not generated by PMDs, and
hence are not reported via ethdev extended statistics.

Metric information is populated using a push model, where
producers update the values contained within the metric
library by calling an update function on the relevant metrics.
Consumers receive metric information by querying the central
metric data, which is held in shared memory.

71f2384328 eventdev: introduce event driven programming model
In a polling model, lcores poll ethdev ports and associated
rx queues directly to look for packet. In an event driven model,
by contrast, lcores call the scheduler that selects packets for
them based on programmer-specified criteria. Eventdev library
adds support for event driven programming model, which offer
applications automatic multicore scaling, dynamic load balancing,
pipelining, packet ingress order maintenance and
synchronization services to simplify application packet processing.

By introducing event driven programming model, DPDK can support
both polling and event driven programming models for packet processing,
and applications are free to choose whatever model
(or combination of the two) that best suits their needs.

This patch adds the eventdev specification header file.
