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.

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.

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
enabled (http://dpdk.org/ml/archives/dev/2015-November/028660.html).
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.

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.

for those jobs is almost the same as in original application.
- stats is moved to rte_alarm callback to not introduce overhead of

- stats are expanded to show rte_jobstats statistics.
- added new parameter '-l' to automatic thousands separator.
Comparing original l2fwd and l2fwd-jobstats apps will show approach what

- Total and % of fwd and flush execution time
- management time - overhead of rte_timer + overhead of rte_jobstats

Then commit 815cfb7925bb6de ("fix link of combined shared library using CC")

Because CPU_LDFLAGS is an exported variable, the prefixing is done twice.

The Packet Framework pipeline library provides a standard methodology
(logically similar to OpenFlow) for rapid development of complex packet
processing pipelines out of ports, tables and actions.
A pipeline is constructed by connecting its input ports to its output ports
through a chain of lookup tables. As result of lookup operation into the
current table, one of the table entries (or the default table entry, in case
of lookup miss) is identified to provide the actions to be executed on the
current packet and the associated action meta-data.
The behavior of user actions is defined through the configurable table action
handler, while the reserved actions define the next hop for the current packet
(either another table, an output port or packet drop) and are handled
transparently by the framework.

The distributor is a component which is designed to pass packets
one-at-a-time to workers, with dynamic load balancing. Using the RSS
field in the mbuf as a tag, the distributor tracks what packet tag is
being processed by what worker and then ensures that no two packets with
the same tag are in-flight simultaneously. Once a tag is not in-flight,
then the next packet with that tag will be sent to the next available
core.
