8d54b1ec4a ethdev: remove Rx header split port offload
As announced in the deprecation note, remove the Rx offload flag
'RTE_ETH_RX_OFFLOAD_HEADER_SPLIT' and 'split_hdr_size' field from
the structure 'rte_eth_rxmode'. Meanwhile, the place where the examples
and apps initialize the 'split_hdr_size' field, and where the drivers
check if the 'split_hdr_size' value is 0 are also removed.

User can still use `RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT` for per-queue packet
split offload, which is configured by 'rte_eth_rxseg_split'.

4ed8904955 remove prefix to some local macros in apps and examples
RTE_TEST_[RT]X_DESC_DEFAULT and RTE_TEST_[RT]X_DESC_MAX macros have been
copied in a lot of app/ and examples/ code.
Those macros are local to each program.

They are not related to a DPDK public header/API, drop the RTE_TEST_
prefix.

9a212dc06c doc: use code snippets in sample app guides
Currently the sample app user guides use hard coded code snippets,
this patch changes these to use literalinclude which will dynamically
update the snippets as changes are made to the code.
This was introduced in commit 413c75c33c ("doc: show how to include
code in guides"). Comments within the sample apps were updated to
accommodate this as part of this patch. This will help to ensure that
the code within the sample app user guides is up to date and not out

ce6b8c3154 examples: fix port mask parsing failure handling
Giving invalid or zero portmask as command line option to
these applications will have an unexpected response.
The reason behind this is that the return value of function
that parses portmask is stored in a variable whose datatype is
unsigned int, hence returning -1 in case of zero or
invalid portmask causes an unexpected behaviour.
If we return 0 instead of -1 this issue can be resolved.
The program already contains the functionality to print
"invalid portmask" and program usage if zero is returned.

8549295db0 build/pkg-config: improve static linking flags
Rather than setting -Bstatic in the linker flags when doing a static link,
and then having to explicitly set -Bdynamic again afterwards, we can update
the pkg-config file to use -l:libfoo.a syntax to explicitly refer to the
static library in question. Since this syntax is not supported by meson's
pkg-config module directly, we can post-process the .pc files instead to
adjust them.

Once done, we can simplify the examples' makefiles and the docs by removing
the explicit static flag.

e9c6594264 examples: detect default build directory
Most examples have in their makefiles a default RTE_TARGET directory to be
used in case RTE_TARGET is not set. Rather than just using a hard-coded
default, we can instead detect what the build directory is relative to
RTE_SDK directory.

This fixes a potential issue for anyone who continues to build using
"make install T=x86_64-native-linuxapp-gcc" and skips setting RTE_TARGET
explicitly, instead relying on the fact that they were building in a
directory which corresponded to the example default path - which was
changed to "x86_64-native-linux-gcc" by commit 218c4e68c1 ("mk: use

Rather than renaming the configs we can just duplicate the existing ones
with the new names using symlinks, and use the new names exclusively
internally. ["make showconfigs" also only shows the new names to keep the
list short] The result is that backward compatibility is kept fully but any
new builds or development can be done using the newer names, i.e.  both
"make config T=x86_64-native-linuxapp-gcc" and "T=x86_64-native-linux-gcc"

ab3ce1e0c1 ethdev: remove old offload API
In DPDK 17.11, the ethdev offloads API has changed:
	commit cba7f53b71 ("ethdev: introduce Tx queue offloads API")
	commit ce17eddefc ("ethdev: introduce Rx queue offloads API")
The new API is documented in the programmer's guide:
	http://doc.dpdk.org/guides/prog_guide/poll_mode_drv.html#hardware-offload

For reminder, the main concepts in the new API were:
	- All offloads are disabled by default
	- Distinction between per port and per queue offloads.

The transition bits are now removed:
	- Translation of the old API in ethdev
	- rte_eth_conf.rxmode.ignore_offload_bitfield
	- ETH_TXQ_FLAGS_IGNORE

The old API bits are now removed:
	- Rx per-port rte_eth_conf.rxmode.[bit-fields]
	- Tx per-queue rte_eth_txconf.txq_flags
	- ETH_TXQ_FLAGS_NO*

fa47405cc1 ethdev: remove experimental flag of ports enumeration
The basic operations for ports enumeration should not be
considered as experimental in DPDK 18.05.

The iterator RTE_ETH_FOREACH_DEV was introduced in DPDK 17.05.
It uses the function the rte_eth_find_next_owned_by() to get
only ownerless ports. Its API can be considered stable.
So the flag experimental is removed from rte_eth_find_next_owned_by().

The flag experimental is removed from rte_eth_dev_count_avail()
which is the new name of the old function rte_eth_dev_count().

The flag experimental is set to rte_eth_dev_count_total()
in the .c file for consistency with the declaration in the .h file.

A lot of internal applications are fixed to not allow experimental API.

d9a42a69fe ethdev: deprecate port count function
Some DPDK applications wrongly assume these requirements:
    - no hotplug, i.e. ports are never detached
    - all allocated ports are available to the application

Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.

In order to fix this common mistake in all external applications,
the function rte_eth_dev_count is deprecated, while introducing
the new functions rte_eth_dev_count_avail and rte_eth_dev_count_total.

a9dbe18022 fix ethdev port id validation
Some DPDK applications wrongly assume these requirements:
    - no hotplug, i.e. ports are never detached
    - all allocated ports are available to the application

Such application assume a valid port index is in the range [0..count[.

There are three consequences when using such wrong design:
    - new ports having an index higher than the port count won't be valid
    - old ports being detached (RTE_ETH_DEV_UNUSED) can be valid

Such mistake will be less common with growing hotplug awareness.

8728ccf376 fix ethdev ports enumeration
Some DPDK applications wrongly assume these requirements:
    - no hotplug, i.e. ports are never detached
    - all allocated ports are available to the application

Such application iterates over ports by its own mean.
The most common pattern is to request the port count and
assume ports with index in the range [0..count[ can be used.

There are three consequences when using such wrong design:
    - new ports having an index higher than the port count won't be seen
    - old ports being detached (RTE_ETH_DEV_UNUSED) can be seen as ghosts
    - failsafe sub-devices (RTE_ETH_DEV_DEFERRED) will be seen by the application

Such mistake will be less common with growing hotplug awareness.
All applications and examples inside this repository - except testpmd -
must be fixed to use the iterator RTE_ETH_FOREACH_DEV.

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.

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

0eba4ade65 examples: put app name and sources at top of makefiles
Reorder the text in the makefiles, so that the app name and the source
files are listed first. This then will allow them to be shared later in a
combined makefile building with pkg-config and RTE_SDK-based build system.

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,\
	ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\
	l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\
	link_status_interrupt,load_balancer,packet_ordering,ptpclient,\
	qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\
	timer,vhost,vhost_scsi,vmdq,vmdq_dcb
