295968d174 ethdev: add namespace
Add 'RTE_ETH' namespace to all enums & macros in a backward compatible
way. The macros for backward compatibility can be removed in next LTS.
Also updated some struct names to have 'rte_eth' prefix.

All internal components switched to using new names.

Syntax fixed on lines that this patch touches.

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
of sync with the actual code.

64051bb1f1 devargs: unify scratch buffer storage
In current design, legacy parser rte_devargs_parse() saved scratch
buffer to devargs.args while new parser rte_devargs_layers_parse() saved
to devargs.data. Code using devargs had to know the difference and
cleaned up memory accordingly - error prone.

This patch unifies scratch buffer to data field, introduces
rte_devargs_reset() function to wrap the memory clean up logic.

27b549c12d examples/multi_process: fix build on Ubuntu 20.04
Two warnings are reported by gcc 9.3.0 on Ubuntu 20.04.

When producing a printable mac address the buffer was appropriately sized
for holding the mac address exactly, but the actual snprintf included a
'\n' character at the end, which means that the snprintf technically is
getting truncated i.e. the \n would not be added due to lack of space.
This gets flagged as a problem by modern versions of gcc, e.g. on Ubuntu
20.04.

main.c:77:37: warning: ‘__builtin___snprintf_chk’ output truncated
  before the last format character [-Wformat-truncation=]
   77 |     "%02x:%02x:%02x:%02x:%02x:%02x\n",
      |                                     ^

Since the \n is getting stripped anyway, we can fix the issue by just
removing it. In the process we can switch to using the standard ethernet
address formatting function from rte_ether.h.

The other warning is about possible string truncation when getting the
RX queue name:

In file included from init.c:36:
init.c: In function ‘init’:
../shared/common.h:38:28: warning: ‘%u’ directive output may be truncated
  writing between 1 and 10 bytes into a region of size 8
  [-Wformat-truncation=]
   38 | #define MP_CLIENT_RXQ_NAME "MProc_Client_%u_RX"
      |                            ^~~~~~~~~~~~~~~~~~~~
../shared/common.h:52:35: note: in expansion of macro ‘MP_CLIENT_RXQ_NAME’
   52 |  snprintf(buffer, sizeof(buffer), MP_CLIENT_RXQ_NAME, id);
      |                                   ^~~~~~~~~~~~~~~~~~

This is a false positive, as the value of the "id" is limited to 255,
being stored in the app as a uint8_t value, removing the possibility of
the %u being replaced by anything other then 3 characters max (rather than
up to 10 as thought by the compiler). Therefore, the warning can be easily
removed by changing the type of the "id" parameter to the local function
from "unsigned" to "uint8_t" also, ensuring the compiler is aware of the
range limit.

6b124806a3 examples/multi_process: fix client crash with sparse ports
The mp_client crashes if run on Azure or any system where ethdev
ports are owned. In that case, the tx_buffer and tx_stats for the
real port were initialized correctly, but the wrong port was used.

For example if the server has Ports 3 and 5. Then calling
rte_eth_tx_buffer_flush on any other buffer will dereference null
because the tx buffer for that port was not allocated.

Also:
   - the flush code is common enough that it should not be marked
     unlikely
   - combine conditions to reduce indentation
   - avoid unnecessary if() if sent is zero.

snprintf guarantees to always correctly place a null terminator
in the buffer string. So manually placing a null terminator
in a buffer right after a call to snprintf is redundant code.

Additionally, there is no need to use 'sizeof(buffer) - 1' in snprintf as this
means we are not using the last character in the buffer. 'sizeof(buffer)' is
enough.

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

218c4e68c1 mk: use linux and freebsd in config names
Rather than using linuxapp and bsdapp everywhere, we can change things to

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"

3504db92b5 examples/multi_process: remove l2fwd fork example
l2fwd_fork relies on a multiprocess model that DPDK does not support
(calling rte_eal_init() before fork()), in particular in light of recent
EAL changes like the multiproess communication channel.

This example can mislead users into thinking this is a supported
multiprocess model; hence, this commit removes this example and the
corresponding user guide documentation as well.

This patch was made following this mailing list discussion:

ed3077c165 examples: make Linux environment check consistent
Some Makefiles are using CONFIG_RTE_EXEC_ENV and others
are using CONFIG_RTE_EXEC_ENV_LINUXAPP.
Use the latter one for consistency.
We could remove CONFIG_RTE_EXEC_ENV later if considered useless.

4f5701f28b examples: fix RSS hash function configuration
ethdev layer introduced checks for application requested RSS hash
functions and returns error for ones unsupported by hardware

This check breaks some sample applications which blindly configures
RSS hash functions without checking underlying hardware support.

Updated examples to mask out unsupported RSS has functions during device
configuration.
Prints a log if configuration values updated by this check.

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.

Fixes: 8728ccf376 ("fix ethdev ports enumeration")
Fixes: d9a42a69fe ("ethdev: deprecate port count function")
Fixes: e70e26861e ("net/mvpp2: fix build")

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.
All applications and examples inside this repository - except testpmd -
must be fixed to use the function rte_eth_dev_is_valid_port.
