The following APIs's are implemented in the
librte_flow_classify library:

rte_flow_classifier_create
rte_flow_classifier_free
rte_flow_classifier_query
rte_flow_classify_table_create
rte_flow_classify_table_entry_add
rte_flow_classify_table_entry_delete

The following librte_table API's are used:
f_create to create a table.
f_add to add a rule to the table.
f_del to delete a rule from the table.
f_free to free a table
f_lookup to match packets with the rules.

The library supports counting of IPv4 five tupple packets only,
ie IPv4 UDP, TCP and SCTP packets.

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
devices.

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.

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.

- A back-end node, which has a hash table where node checks,

56b6ef874f efd: new Elastic Flow Distributor library
Elastic Flow Distributor (EFD) is a distributor library that uses
perfect hashing to determine a target/value for a given incoming flow key.
It has the following advantages:

- First, because it uses perfect hashing, it does not store
  the key itself and hence lookup performance is not dependent
  on the key size.

- Second, the target/value can be any arbitrary value hence
  the system designer and/or operator can better optimize service rates
  and inter-cluster network traffic locating.

- Third, since the storage requirement is much smaller than a hash-based
  flow table (i.e. better fit for CPU cache), EFD can scale to
  millions of flow keys.
  Finally, with current optimized library implementation performance
  is fully scalable with number of CPU cores.

This commit introduces 8-bit, 16-bit, 32bit, 64bit I/O device
memory read/write operations along with the relaxed versions.

The weakly-ordered machine like ARM needs additional I/O barrier for
device memory read/write access over PCI bus.
By introducing the eal abstraction for I/O device memory read/write access,
The drivers can access I/O device memory in architecture agnostic manner.

The relaxed version does not have additional I/O memory barrier, useful in
accessing the device registers of integrated controllers which
implicitly strongly ordered with respect to memory access.

b1a4b4cbc0 ethdev: introduce generic flow API
This new API supersedes all the legacy filter types described in
rte_eth_ctrl.h. It is slightly higher level and as a result relies more on
PMDs to process and validate flow rules.

Benefits:

- A unified API is easier to program for, applications do not have to be
  written for a specific filter type which may or may not be supported by
  the underlying device.

- The behavior of a flow rule is the same regardless of the underlying
  device, applications do not need to be aware of hardware quirks.

- Extensible by design, API/ABI breakage should rarely occur if at all.

- Documentation is self-standing, no need to look up elsewhere.

Existing filter types will be deprecated and removed in the near future.

600086ebb7 doc: disable doxygen member sorting
Disabled the doxygen option to sort member data so that functions
and struct memebers are listed in order of definition in the
brief and main sections.

Previously they were sorted in the brief section and were in
definition order in the main section.

2ee98e69e1 mbuf: clean old refcnt option
CONFIG_RTE_MBUF_SCATTER_GATHER was renamed into CONFIG_RTE_MBUF_REFCNT
by commit 62814bc2e9 and removed by commit 4769bc5a27.
Some traces remain because of delayed patches.

It can also be removed from doxygen config.
It is now poisoned in rte_mbuf.h to warn any misuse.

Fixes: d0dff9ba44 ("doc: sample application user guide")
Fixes: fc1f2750a3 ("doc: programmers guide")
Fixes: 4769bc5a27 ("mbuf: remove build option to disable refcnt")

597b0f74e2 jobstats: new library
This library provide API to measure time spend in particular parts of
code and to calculate optimal polling time.

To calculate a those statistics application code need to be divided into
parts (called jobs) that do something. It is up to application to decide
what is considered a job.

Series of jobs must be surrounded with the rte_jobstats_context_start()
and rte_jobstats_context_finish() calls. After that, jobs might be
started.  Each job must be surrounded with rte_jobstats_start() and
rte_jobstats_finish() calls.

After job finishes its execution, period in which it should be called
again is adjusted. It might be used to minimize time wasted on
unnecessary polls/calls. Adjustment is based on data provided by job
itself (ex: number of packets it processed).

After all jobs in serie are executed fallowing statistics are updated
and might be used by application. Statistics can be reset. Some of
provided statistic data:
 - total/min/max execution - time spent in executing jobs.
 - total/min/max management - time spent outside execution area. This
value might be used to measure overhead of scheduling jobs. This time
also contains overhead of rte_jobstats library itself.
 - number of loops that executed at least one job
 - executed jobs
 - time when statistics were reset.

Each job provide total/min/max execution time and execution count
statistics.

4b2fd987d8 eal: split atomic operations to architecture specific
This patch first adds architecture specific directories to eal.
Then split the atomic operations to architecture specific and generic files.
Architecture specific files are put into the corresponding architecture
directory and common header are put into generic directory.

Update documentation generation with new generic/ directory.
