30883f3e1d doc: use new crypto driver names
Crypto driver names were changed in 16.11,
but some guides were still using the old ones
(which are still valid, only kept for compatibility
reasons).

To keep consistency and avoid confusion, all guides
should be using the same driver names.

7146aa19ac ethdev: introduce lock-free Tx queue capability
Introducing the DEV_TX_OFFLOAD_MT_LOCKFREE TX capability flag.
if a PMD advertises DEV_TX_OFFLOAD_MT_LOCKFREE capable, multiple threads
can invoke rte_eth_tx_burst() concurrently on the same tx queue without
SW lock. This PMD feature will be useful in the following use cases and
found in the OCTEON family of NPUs.

1) Remove explicit spinlock in some applications where lcores
to TX queues are not mapped 1:1.
example: OVS has such instance
https://github.com/openvswitch/ovs/blob/master/lib/netdev-dpdk.c#L299
https://github.com/openvswitch/ovs/blob/master/lib/netdev-dpdk.c#L1859
See the the usage of tx_lock spinlock.

2) In the eventdev use case, avoid dedicating a separate TX core for
transmitting and thus enables more scaling as all workers can
send the packets.

Add header files, update .map files with new service

7a364faef1 cryptodev: remove crypto device type enumeration
Changes device type identification to be based on a unique
driver id replacing the current device type enumeration, which needed
library changes every time a new crypto driver was added.

The driver id is assigned dynamically during driver registration using
the new macro RTE_PMD_REGISTER_CRYPTO_DRIVER which returns a unique
uint8_t identifier for that driver. New APIs are also introduced
to allow retrieval of the driver id using the driver name.

AEAD operation parameters can be set in the new
aead structure, in the crypto operation.
This structure is within a union with the cipher

- AEAD: using the aead structure

- Cipher only: using only the cipher structure

- Auth only: using only the authentication structure

- Cipher-then-auth/Auth-then-cipher: using both cipher
  and authentication structures

acf8616901 cryptodev: add auth IV
Authentication algorithms, such as AES-GMAC or the wireless
algorithms (like SNOW3G) use IV, like cipher algorithms.
So far, AES-GMAC has used the IV from the cipher structure,
and the wireless algorithms have used the AAD field,
which is not technically correct.

Therefore, authentication IV parameters have been added,
so API is more correct. Like cipher IV, auth IV is expected
to be copied after the crypto operation.

Add new meta pattern item RTE_FLOW_TYPE_ITEM_FUZZY in flow API.

This is for device that support fuzzy match option.
Usually a fuzzy match is fast but the cost is accuracy.
i.e. Signature Match only match pattern's hash value, but it is
possible that two different patterns have the same hash value.

Matching accuracy level can be configured by subfield threshold.
Driver can divide the range of threshold and map to different
accuracy levels that device support.

323f811a4a ethdev: add isolated mode to flow API
Isolated mode can be requested by applications on individual ports to avoid
ingress traffic outside of the flow rules they define.

Besides making ingress more deterministic, it allows PMDs to safely reuse
resources otherwise assigned to handle the remaining traffic, such as
global RSS configuration settings, VLAN filters, MAC address entries,
legacy filter API rules and so on in order to expand the set of possible
flow rule types.

To minimize code complexity, PMDs implementing this mode may provide
partial (or even no) support for flow rules when not enabled (e.g. no
priorities, no RSS action). Applications written to use the flow API are
therefore encouraged to enable it.

Once effective, leaving isolated mode may not be possible depending on PMD
implementation.

79c913a42f ethdev: retrieve xstats by ID
Extended xstats API in ethdev library to allow grouping of stats
logically so they can be retrieved per logical grouping  managed
by the application.
Added new functions rte_eth_xstats_get_names_by_id and
rte_eth_xstats_get_by_id using additional arguments (in compare
to rte_eth_xstats_get_names and rte_eth_xstats_get) - array of ids
and array of values.

doc: add description for modified xstats API
Documentation change for new extended statistics API functions.
The old API only allows retrieval of *all* of the NIC statistics
at once. Given this requires a MMIO read PCI transaction per statistic
it is an inefficient way of retrieving just a few key statistics.
Often a monitoring agent only has an interest in a few key statistics,
and the old API forces wasting CPU time and PCIe bandwidth in retrieving
*all* statistics; even those that the application didn't explicitly
show an interest in.
The new, more flexible API allow retrieval of statistics per ID.
If a PMD wishes, it can be implemented to read just the required
NIC registers. As a result, the monitoring application no longer wastes
PCIe bandwidth and CPU time.

producers update the values contained within the metric
library by calling an update function on the relevant metrics.

af14759181 vhost: introduce API to start a specific driver
We used to use rte_vhost_driver_session_start() to trigger the vhost-user
session. It takes no argument, thus it's a global trigger. And it could
be problematic.

The issue is, currently, rte_vhost_driver_register(path, flags) actually
tries to put it into the session loop (by fdset_add). However, it needs
a set of APIs to set a vhost-user driver properly:
  * rte_vhost_driver_register(path, flags);
  * rte_vhost_driver_set_features(path, features);
  * rte_vhost_driver_callback_register(path, vhost_device_ops);

If a new vhost-user driver is registered after the trigger (think OVS-DPDK
that could add a port dynamically from cmdline), the current code will
effectively starts the session for the new driver just after the first
API rte_vhost_driver_register() is invoked, leaving later calls taking
no effect at all.

To handle the case properly, this patch introduce a new API,
rte_vhost_driver_start(path), to trigger a specific vhost-user driver.
To do that, the rte_vhost_driver_register(path, flags) is simplified
to create the socket only and let rte_vhost_driver_start(path) to
actually put it into the session loop.

Meanwhile, the rte_vhost_driver_session_start is removed: we could hide
the session thread internally (create the thread if it has not been
created). This would also simplify the application.

NOTE: the API order in prog guide is slightly adjusted for showing the
correct invoke order.

ecaed092b6 ring: return remaining entry count when dequeuing
Add an extra parameter to the ring dequeue burst/bulk functions so that
those functions can optionally return the amount of remaining objs in the
ring. This information can be used by applications in a number of ways,
for instance, with single-consumer queues, it provides a max
dequeue size which is guaranteed to work.

77dd306427 ring: remove watermark support
Remove the watermark support. A future commit will add support for having
enqueue functions return the amount of free space in the ring, which will
allow applications to implement their own watermark checks, while also
being more useful to the app.

82cb88375c ring: remove the yield when waiting for tail update
There was a compile time setting to enable a ring to yield when
it entered a loop in mp or mc rings waiting for the tail pointer update.
Build time settings are not recommended for enabling/disabling features,
and since this was off by default, remove it completely. If needed, a
runtime enabled equivalent can be used.

8c82198978 ring: remove debug setting
The debug option only provided statistics to the user, most of
which could be tracked by the application itself. Remove this as a
compile time option, and feature, simplifying the code.

feb9f680cd mk: optimize directory dependencies
Before this patch, the management of dependencies between directories
had several issues:

- the generation of .depdirs, done at configuration is slow: it can take
  more than one minute on some slow targets (usually ~10s on a standard
  PC without -j).

- for instance, it is possible to express a dependency like:
  - app/foo depends on lib/librte_foo
  - and lib/librte_foo depends on app/bar
  But this won't work because the directories are traversed with a
  depth-first algorithm, so we have to choose between doing 'app' before
  or after 'lib'.

- the script depdirs-rule.sh is too complex.

- we cannot use "make -d" for debug, because the output of make is used for
  the generation of .depdirs.

This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.

After this commit, "make config" is almost immediate.
