8744d7a945 mk: restrict CPU flags list
When compiling each file, the CPU flags are given as RTE_MACHINE_CPUFLAG_*
and in the list RTE_COMPILE_TIME_CPUFLAGS.

RTE_MACHINE_CPUFLAG_* are used to check the CPU features when compiling.

The list RTE_COMPILE_TIME_CPUFLAGS is used only to check the CPU at
runtime in the function rte_cpu_check_supported(). So it is not needed to
define this list for every files.
That's why RTE_COMPILE_TIME_CPUFLAGS is removed from the common variable
MACHINE_CFLAGS and is added only to the CFLAGS of eal_common_cpuflags.c.

9f8d48e569 mk: fix linker script when re-building
The linker script is generated by simply finding all libraries in
RTE_OUTPUT/lib.

The issue shows up when re-building the DPDK, hence already having a
linker script in that directory, resulting in the linker script
including itself.

That does not play well with the linker.

Simply filtering the linker script from all the found libraries solves
the problem.

d4b42133d8 port: add pcap file source
Originally, source ports in librte_port is an input port used as packet
generator. Similar to Linux kernel /dev/zero character device, it
generates null packets. This patch adds optional PCAP file support to
source port: instead of sending NULL packets, the source port generates
packets copied from a PCAP file. To increase the performance, the packets
in the file are loaded to memory initially, and copied to mbufs in circular
manner. Users can enable or disable this feature by setting
CONFIG_RTE_PORT_PCAP compiler option "y" or "n".

If the experimental CONFIG_RTE_LIBRTE_CRYPTODEV is disabled, build of

94b0ad8e0a null_crypto: add driver for null crypto operations
This patch provides the implementation of a NULL crypto PMD, which supports
NULL cipher and NULL authentication operations, which can be chained together
as follows:

- Authentication Only
- Cipher Only
- Authentication then Cipher
- Cipher then Authentication

As this is a NULL operation device the crypto operations which are submitted for
processing are not actually modified and are stored in a queue pairs processed
packets ring ready for collection when rte_cryptodev_burst_dequeue() is called.

The patch also contains the related unit tests function to test the PMDs
supported operations.

3aafc423cf snow3g: add driver for SNOW 3G library
Added new SW PMD which makes use of the libsso SW library,
which provides wireless algorithms SNOW 3G UEA2 and UIA2
in software.

This PMD supports cipher-only, hash-only and chained operations
("cipher then hash" and "hash then cipher") of the following
algorithms:
- RTE_CRYPTO_SYM_CIPHER_SNOW3G_UEA2
- RTE_CRYPTO_SYM_AUTH_SNOW3G_UIA2

The SNOW 3G hash and cipher algorithms, which are enabled
by this crypto PMD are implemented by Intel's libsso software
library. For library download and build instructions,
see the documentation included (doc/guides/cryptodevs/snow3g.rst)

b2bb3a5daa mk: stop on warning only in developer build
Add RTE_DEVEL_BUILD make-variable which can be used to do things
differently when doing development vs building a release,
autodetected from source root .git presence and overridable via
commandline. It is used it to enable -Werror compiler flag and may
be extended to other checks.

Failing build on warnings is a useful developer tool but its bad
for release tarballs which can and do get built with newer
compilers than what was used/available during development. Compilers
routinely add new warnings so code which built silently with cc X
might no longer do so with X+1. This doesn't make the existing code
any more buggier and failing the build in this case does not help
to improve the quality of an already released version either.

This change the default flags which can be tuned with EXTRA_CFLAGS.

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.

initially suggested by Neil Horman.

Requiring applications to know about library internal details like
dependencies to external helper libraries is a limitation of
static linkage, shared libraries should always know their own
dependencies for sane operation. This is especially highlighted
with dlopen()'ed items, having applications link against about plugin
internal dependencies goes on the side of absurd.

Note that linking with a shared combined library still requires to
know the internal dependencies.

a08634a224 mk: prepare dependencies in shared libraries not combined
Some DPDK libraries have a dependency.
The Mellanox drivers embed this declaration in shared library case.
So the application do not need to know the dependency when linking.
But it cannot work with static libraries or the combined one.
Note that Mellanox drivers are currently not supported in a shared
combined library case.

Most of the DPDK libraries declare their dependencies to be linked
with the application in every cases, even when using drivers as
shared library plugins.
This patch improves the condition used for Mellanox drivers, so that
it can be applied to other drivers without breaking the shared
combined library case.

Building RTE_LIBRTE_PMD_XENVIRT was broken when RTE_BUILD_COMBINE_LIBS was

Now the underlying issue is rather simple, the xen code needs libxenstore.
But rte.app.mk so far only considered that when RTE_BUILD_COMBINE_LIBS was
disabled.
While it is correct to create the DPDK sublib linking only in the
RTE_BUILD_COMBINE_LIBS=n case, the libxenstore should be added to the linked
libs in any case if RTE_LIBRTE_PMD_XENVIRT is enabled.

And trying to load it in testpmd triggers this error:

[...]
EAL: librte_pmd_mlx4.so: undefined symbol: ibv_query_port
[...]

After some strace, the problem comes from the --as-needed option passed to the
linker.

It is safer to specify libraries we depend on after the objects we are linking
into a shared library, especially when the linker is invoked with options like
--as-needed.

da8dcc27f6 hash: use armv8-a CRC32 instructions
armv8-a has optional CRC32 extension, march=armv8-a+crc enables code
generation for the ARMv8-A architecture together with
the optional CRC32 extensions.

added RTE_MACHINE_CPUFLAG_CRC32 to detect the availability of
CRC32  extension in compile time. At run-time, The RTE_CPUFLAG_CRC32
can be used to find the availability.

armv8-a+crc target support added in GCC 4.9,
Used inline assembly and emulated __ARM_FEATURE_CRC32 to work
with tool-chain < 4.9

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).

78c8709b5d mbuf_offload: introduce library to attach offloads to mbuf
This library add support for adding a chain of offload operations to a
mbuf. It contains the definition of the rte_mbuf_offload structure as
well as helper functions for attaching  offloads to mbufs and a mempool
management functions.

This initial implementation supports attaching multiple offload
operations to a single mbuf, but only a single offload operation of a
specific type can be attach to that mbuf.

abef3dd62e szedata2: add new poll mode driver
Add virtual PMD which communicates with COMBO cards through sze2
layer using libsze2 library.

Since link_speed is uint16_t, there can not be used number for 100G
speed, therefore link_speed is set to ETH_LINK_SPEED_10G until the
type of link_speed is solved.
