948fd64bef mk: replace the combined library with a linker script
The physically linked-together combined library has been an increasing
source of problems, as was predicted when library and symbol versioning
was introduced. Replace the complex and fragile construction with a
simple linker script which achieves the same without all the problems,
remove the related kludges from eg mlx drivers.

Since creating the linker script is practically zero cost, remove the
config option and just create it always.

Based on a patch by Sergio Gonzales Monroy, linker script approach
initially suggested by Neil Horman.

924e84f873 aesni_mb: add driver for multi buffer based crypto
This patch provides the initial implementation of the AES-NI multi-buffer
based crypto poll mode driver using DPDK's new cryptodev framework.

This PMD is dependent on Intel's multibuffer library, see the whitepaper
"Fast Multi-buffer IPsec Implementations on Intel® Architecture
Processors", see ref 1 for details on the library's design and ref 2 to
download the library itself. This initial implementation is limited to
supporting the chained operations of "hash then cipher" or "cipher then
hash" for the following cipher and hash algorithms:

Cipher algorithms:
  - RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)

Authentication algorithms:
  - RTE_CRYPTO_AUTH_SHA1_HMAC
  - RTE_CRYPTO_AUTH_SHA256_HMAC
  - RTE_CRYPTO_AUTH_SHA512_HMAC
  - RTE_CRYPTO_AUTH_AES_XCBC_MAC

Important Note:
Due to the fact that the multi-buffer library is designed for
accelerating IPsec crypto operation, the digest's generated for the HMAC
functions are truncated to lengths specified by IPsec RFC's, ie RFC2404
for using HMAC-SHA-1 with IPsec specifies that the digest is truncate
from 20 to 12 bytes.

Build instructions:
To build DPDK with the AESNI_MB_PMD the user is required to download
(ref 2) and compile the multi-buffer library on there system before
building DPDK. The environmental variable AESNI_MULTI_BUFFER_LIB_PATH
must be exported with the path where you extracted and built the multi
buffer library and finally set CONFIG_RTE_LIBRTE_PMD_AESNI_MB=y in
config/common_linuxapp.

Current status: It's doesn't support crypto operation
across chained mbufs, or cipher only or hash only operations.

1703e94ac5 qat: add driver for QuickAssist devices
This patch adds a PMD for the Intel Quick Assist Technology DH895xxC
hardware accelerator.

This patch depends on a QAT PF driver for device initialization. See
the file docs/guides/cryptodevs/qat.rst for configuration details

This patch supports a limited subset of QAT device functionality,
currently supporting chaining of cipher and hash operations for the
following algorithmsd:

Cipher algorithms:
  - RTE_CRYPTO_CIPHER_AES_CBC (with 128-bit, 192-bit and 256-bit keys supported)

Hash algorithms:
  - RTE_CRYPTO_AUTH_SHA1_HMAC
  - RTE_CRYPTO_AUTH_SHA256_HMAC
  - RTE_CRYPTO_AUTH_SHA512_HMAC
  - RTE_CRYPTO_AUTH_AES_XCBC_MAC

Some limitation on this patchset which shall be contributed in a
subsequent release:
 - Chained mbufs are not supported.
 - Hash only is not supported.
 - Cipher only is not supported.
 - Only in-place is currently supported (destination address is
   the same as source address).
 - Only supports session-oriented API implementation (session-less
   APIs are not supported).

fafcc11985 mem: rework memzone to be allocated by malloc
In the current memory hierarchy, memsegs are groups of physically
contiguous hugepages, memzones are slices of memsegs and malloc further
slices memzones into smaller memory chunks.

This patch modifies malloc so it partitions memsegs instead of memzones.
Thus memzones would call malloc internally for memory allocation while
maintaining its ABI.

During initialization malloc sets all available memory as part of the heaps.
CONFIG_RTE_MALLOC_MEMZONE_SIZE was used to specify the default memory
block size to expand the heap. The option is not used/relevant anymore,
so we remove it.

Remove free_memseg field from internal mem config structure as it is
not used anymore.
Also remove code in ivshmem that was setting up free_memseg on init.

It would be possible to free memzones and therefore any other structure
based on memzones, ie. mempools

506f51cc0d mk: enable next abi preview
When a change makes really hard to keep ABI compatibility,
instead of waiting next release to break the ABI, it is smoother
to introduce the new code as a preview and disable it when packaging.
The flag RTE_NEXT_ABI must be used to "ifdef" the new code.
When the release is out, a dynamically linked application can use
the new shared libraries with the old ABI while developpers can prepare
their application for the next ABI by reading the deprecation notice
and easily testing the new code.
When starting the next release cycle, the "ifdefs" will be removed
and the ABI break will be marked by incrementing LIBABIVER. The map
files will also be updated.

The default value is enabled to be developer compliant.
The packagers must disable it as done in pkg/dpdk.spec.
When enabled, all shared library numbers are incremented by appending
a minor .1 to the old ABI number. In the next release, only impacted
libraries will have a major +1 increment.
The impacted libraries must provide an alternative map file to use
with this option.

The ABI policy is updated.

ad37b97d8d mlx4: remove old VMware compatibility code
CONFIG_RTE_LIBRTE_MLX4_COMPAT_VMWARE has no effect since this option enables
MLX4_PMD_COMPAT_VMWARE. This macro is not used by the PMD which expects
MLX4_COMPAT_VMWARE instead.

Because this option does not work and the related code is no longer useful
for VMware (as it actually supports the flow steering API), remove it
entirely.

14b53e27b3 ethdev: fix crash with multiprocess
The data structure for the rx and tx callbacks is local to each process
since it contains function pointers and cannot be shared between
different unique binaries. However, because it is not in
rte_eth_dev_data structure, the array is not getting initialized for
secondary processes - neither is it getting appropriately resized if the
number of RX/TX queues changes. This causes crashes in secondary
processes as they dereference a null pointer in struct rte_eth_dev.

This patch fixes this by introducing an upper-bound on the number of
queues per port that can be configured, and then uses this to make the
array statically sized, thereby avoiding the crashes.

Fixes: 4dc294158c ("ethdev: support optional Rx and Tx callbacks")

c743e50c47 null: new poll mode driver
Null PMD is a driver of the virtual device particularly designed to measure
performance of DPDK PMDs. When an application call rx, Null PMD just allocates
mbufs and returns those. Also tx, the PMD just frees mbufs.

The PMD has following options.
- size: specify packe size allocated by RX. Default packet size is 64.
- copy: specify 1 or 0 to enable or disable copy while RX and TX.
	Default value is 0(disabled).
	This option is used for emulating more realistic data transfer.
	Copy size is equal to packet size.

To use the PMD, enable CONFIG_RTE_BUILD_SHARED_LIB in config file. Then
compile the PMD as shared library. The library can be linked using '-d'
option when an application invokes.

Here is an example.
$ sudo ./testpmd -c f -n 4 -d librte_pmd_null.so \
	--vdev 'eth_null0' --vdev 'eth_null1' -- -i --no-flush-rx

If testpmd is compiled with CONFIG_RTE_BUILD_SHARED_LIB, it may need to
specify more libraries using '-d' option.

7fae69eeff mlx4: new poll mode driver
This PMD manages all variants of Mellanox ConnectX-3 (EN 40, EN 10, Pro EN
40) as well as their virtual functions in SR-IOV context through IB Verbs
(libibverbs) and the dedicated user-space driver (libmlx4).

It is disabled by default due to dependencies on these libraries and only
supports Linux userland at the moment partly because /sys (sysfs) support is
required.

Also claim responsibility in the MAINTAINERS file.

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.

4e01799aea ring: add optional yield to avoid spin forever
Add a sched_yield() syscall if the thread spins for too long,
waiting other thread to finish its operations on the ring.
That gives pre-empted thread a chance to proceed and finish
with ring enqueue/dequeue operation.
The purpose is to reduce contention on the ring.
By ring_perf_test, it doesn't shows additional perf penalty.
