1cfe212ed1 kni: support MAC address change
This patch adds following:
1. Option to configure the mac address during create. Generate random
   address only if the user has not provided any valid address.
2. Inform usespace, if mac address is being changed in linux.
3. Implement default handling of mac address change in the corresponding
   ethernet device.

b114af1603 build: remove architecture flag as default C flag
Any flags added to the project args are automatically added to all builds,
both native and cross-compiled. This is not what we want for the -march
flag as a valid -march for the cross-compile is not valid for pmdinfogen
which is a native-build tool.

Instead we store the march flag as a variable, and add it to the default
cflags for all libs, drivers, examples, etc. This will allow pmdinfogen to
compile successfully in a cross-compilation environment.

1842d194c9 examples: enable linking both static and shared
Since the DPDK build now includes both static and shared libraries, we need
a new way to enable building the examples using either method from the one
installation. To do this, we add in a default "shared" target, and a
separate "static" target which links in the DPDK static libraries. In both
cases, the final application name is symlinked to the last-built static or
shared target, with both binaries able to co-exist in the build directory.

3e5c3d58e1 build: build as both static and shared libs
This patch changes the build process to group all .o files for a driver or
library into a static archive first, and then link the .o files together
into a shared library. This eliminates the need for separate static or
shared object builds when packaging, for instance.

The "default_library" configuration option now only affects the apps and
examples, which are either linked against the static or shared library
versions depending on the value of the option.

22119c4591 examples: use pkg-config in makefiles
Change the example app Makefiles to query if DPDK is installed and
registered using pkg-config. If so, build directly using pkg-config info,
otherwise fall back to using the original build system with RTE_SDK and
RTE_TARGET

This commit changes the makefiles for the basic examples, i.e. those which
do not have multiple subdirectories underneath the main examples dir.
Examples not covered are:

* ethtool
* multi_process
* performance-thread
* quota_watermark
* netmap_compat
* server_node_efd
* vm_power_manager

89f0711f9d examples: build some samples with meson
Add support for having selected example apps built as part of a meson,
ninja build. By default none are built, and those to be built should be
named directly in the -Dexamples='' meson configuration argument.

This is useful for developers working on a feature who want to use a
suitable example, or examples, to test that feature, as they can compile
everything up in one go, and run the example without having to do a ninja
install first.

This commit adds examples which don't consist of multiple apps in
subdirectories to the meson build, so they can be built by default by
passing -Dexamples parameter to meson.

Not included are the following examples:
* ethtool
* multi-process
* netmap_compat
* performance-thread
* quota_watermark
* server_node_efd
* vm_power_manager

To test the apps added here, use the following command, merged to one line,
to add them to your meson build (command to be run inside the build
directory):

meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\
	eventdev_pipeline_sw_pmd, exception_path,helloworld,\
	ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\

Since the processing of crypto operations may take time
due to hardware offload, all the packets may not be available
in the single dequeue command.
So it may happen that there is leakage of cops, and there is
nobody to dequeue the packets because dequeue of crypto ops is
done only once for a particular queue pair even if it has more
packets in flight.

This patch dequeue the packets again if the inflight packets are
more than the max packet burst.

Adding support for inline protocol processing

In ingress side, application will receive regular IP packets, without
any IPsec related info. Application will do a selector check (SP-SA
check) by making use of the metadata from the packet. The
device-specific metadata in mbuf would aid in determing the security
session which processed the packet.

In egress side, the plain packet would be submitted to the driver. The
packet will have optional metadata, which could be used to identify the
security session associated with the packet.

When security offload is enabled, the packet should be forwarded on the
port configured in the SA. Security session will be configured on that
port only, and sending the packet on other ports could result in
unencrypted packets being sent out.

This would have performance improvements too, as the per packet LPM
lookup would be avoided for IPsec packets, in inline mode.

ec36d881f5 eventdev: add implicit release disable capability
This commit introduces a capability for disabling the "implicit" release
functionality for a port, which prevents the eventdev PMD from issuing
outstanding releases for previously dequeued events when dequeuing a new
batch of events.

If a PMD does not support this capability, the application will receive an
error if it attempts to setup a port with implicit releases disabled.
Otherwise, if the port is configured with implicit releases disabled, the
application must release each dequeued event by invoking
rte_event_enqueue_burst() with RTE_EVENT_OP_RELEASE or
RTE_EVENT_OP_FORWARD.
