eeded2044a log: register with standardized names
Let's try to enforce the convention where most drivers use a pmd. logtype
with their class reflected in it, and libraries use a lib. logtype.

Introduce two new macros:
- RTE_LOG_REGISTER_DEFAULT can be used when a single logtype is
  used in a component. It is associated to the default name provided
  by the build system,
- RTE_LOG_REGISTER_SUFFIX can be used when multiple logtypes are used,
  and then the passed name is appended to the default name,

RTE_LOG_REGISTER is left untouched for existing external users
and for components that do not comply with the convention.

There is a new Meson variable log_prefix to adapt the default name
for baseband (pmd.bb.), bus (no pmd.) and mempool (no pmd.) classes.

Note: achieved with below commands + reverted change on net/bonding +
edits on crypto/virtio, compress/mlx5, regex/mlx5

f30e69b41f ethdev: add device flag to bypass auto-filled queue xstats
Queue stats are stored in 'struct rte_eth_stats' as array and array size
is defined by 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag.

As a result of technical board discussion, decided to remove the queue
statistics from 'struct rte_eth_stats' in the long term.

Instead PMDs should represent the queue statistics via xstats, this
gives more flexibility on the number of the queues supported.

Currently queue stats in the xstats are filled by ethdev layer, using
some basic stats, when queue stats removed from basic stats the
responsibility to fill the relevant xstats will be pushed to the PMDs.

During the switch period, temporary 'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS'
device flag is created. Initially all PMDs using xstats set this flag.
The PMDs implemented queue stats in the xstats should clear the flag.

When all PMDs switch to the xstats for the queue stats, queue stats
related fields from 'struct rte_eth_stats' will be removed, as well as
'RTE_ETH_DEV_AUTOFILL_QUEUE_XSTATS' flag.
Later 'RTE_ETHDEV_QUEUE_STAT_CNTRS' compile time flag also can be
removed.

b8f5d2ae75 ethdev: remove forcing stopped state upon close
When closing a port, it is supposed to be already stopped,
and marked as such with "dev_started" state zeroed by the stop API.

Resetting "dev_started" before calling the driver close operation
was hiding the case of not properly stopped port being closed.
The flag "dev_started" is not changed anymore in "rte_eth_dev_close()".

In case the "dev_stop" function is called from "dev_close",
bypassing "rte_eth_dev_stop()" API,
the "dev_started" state must be explicitly reset in the PMD
in order to keep the same behaviour.

fbd1913561 ethdev: remove old close behaviour
The temporary flag RTE_ETH_DEV_CLOSE_REMOVE is removed.
It was introduced in DPDK 18.11 in order to give time for PMDs to migrate.

The old behaviour was to free only queues when closing a port.
The new behaviour is calling rte_eth_dev_release_port() which does
three more tasks:
	- trigger event callback
	- reset state and few pointers
	- free all generic port resources

The private port resources must be released in the .dev_close callback.

The .remove callback should:
	- call .dev_close callback
	- call rte_eth_dev_release_port()
	- free multi-port device shared resources

Despite waiting two years, some drivers have not migrated,
so they may hit issues with the incompatible new behaviour.
After sending emails, adding logs, and announcing the deprecation,
the only last solution is to declare these drivers as unmaintained:
	ionic, liquidio, nfp
Below is a summary of what to implement in those drivers.

* The freeing of private port resources must be moved
from the ".remove(device)" function to the ".dev_close(port)" function.

* If a generic resource (.mac_addrs or .hash_mac_addrs) cannot be freed,
it must be set to NULL in ".dev_close" function to protect from
subsequent rte_eth_dev_release_port() freeing.

* Note 1:
The generic resources are freed in rte_eth_dev_release_port(),
after ".dev_close" is called in rte_eth_dev_close(), but not when
calling ".dev_close" directly from the ".remove" PMD function.
That's why rte_eth_dev_release_port() must still be called explicitly
from ".remove(device)" after calling the ".dev_close" PMD function.

* Note 2:
If a device can have multiple ports, the common resources must be freed
only in the ".remove(device)" function.

* Note 3:
The port is supposed to be in a stopped state when it is closed.
If it is not the case, it is free to the PMD implementation
how to react when trying to close a non-stopped port:
either try to stop it automatically or just return an error.

8459f5ab32 net/ring: fix device pointer on allocation
When a net_ring device is allocated, its device pointer is not set
before calling rte_eth_dev_probing_finish, which is incorrect.

The following:
  commit 96cb195211 ("net/ring: use EAL APIs in PMD specific API")
  commit a6992e9610 ("net/ring: set ethernet device field")

already fixed the same issue in 17.08, which was fine at the time.
Adding the hook rte_eth_dev_probing_finish() however created this bug,
as the eth_dev exposed when this hook is executed is expected to be
complete.

Remove the prior attempts to fix the issue in rte_pmd_ring_probe() and
write the pointer properly in do_eth_dev_ring_create().

(LIBABIVER := numbers, optionally preceded by a comment and optionally
succeeded by an empty line)

The replacement for meson files was done using the following regex:

(version = numbers, optionally preceded by a comment and optionally

f8e9989606 remove useless constructor headers
A constructor is usually declared with RTE_INIT* macros.
As it is a static function, no need to declare before its definition.
The macro is used directly in the function definition.

70815c9eca ethdev: add new offload flag to keep CRC
DEV_RX_OFFLOAD_KEEP_CRC offload flag is added. PMDs that support
keeping CRC should advertise this offload capability.

DEV_RX_OFFLOAD_CRC_STRIP flag will remain one more release
default behavior in PMDs are to keep the CRC until this flag removed

Until DEV_RX_OFFLOAD_CRC_STRIP flag is removed:
- Setting both KEEP_CRC & CRC_STRIP is INVALID
- Setting only CRC_STRIP PMD should strip the CRC
- Setting only KEEP_CRC PMD should keep the CRC
- Not setting both PMD should keep the CRC

A helper function rte_eth_dev_is_keep_crc() has been added to be able to
change the no flag behavior with minimal changes in PMDs.

The PMDs that doesn't report the DEV_RX_OFFLOAD_KEEP_CRC offload can
remove rte_eth_dev_is_keep_crc() checks next release, related code
commented to help the maintenance task.

And DEV_RX_OFFLOAD_CRC_STRIP has been added to virtual drivers since
they don't use CRC at all, when an application requires this offload
virtual PMDs should not return error.

fbe90cdd77 ethdev: add probing finish function
A new hook function is added and called inside the PMDs at the end
of the device probing:
	- in primary process, after allocating, init and config
	- in secondary process, after attaching and local init

This new function is almost empty for now.
It will be used later to add some post-initialization processing.

For the PMDs calling the helpers rte_eth_dev_create() or
rte_eth_dev_pci_generic_probe(), the hook rte_eth_dev_probing_finish()
is called from here, and not in the PMD itself.

Note that the helper rte_eth_dev_create() could be used more,
especially for vdevs, avoiding some code duplication in PMDs.

5f19dee604 drivers/net: do not use private ethdev data
We introduced private rte_eth_dev_data to allow vdev to be created
both in primary process and secondary process(es). This is not
friendly to multi-process model, for example, it leads to port id
contention issue if two processes both find the data entry is free.

And to get stats of primary vdev in secondary, we must allocate
from the pre-defined array so that we can find it.

ffc905f3b8 ethdev: separate driver APIs
Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.

There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.

More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

1e3a958f40 ethdev: fix link autonegotiation value
There are 3 kind of link data in ethdev:
	- capabilities (rte_eth_dev_info)
	- configuration (rte_eth_conf)
	- status (rte_eth_link)

A bit-field is used for capabilities (rte_eth_dev_info.speed_capa) and
configuration (rte_eth_conf.link_speeds).
Bits are defined in ETH_LINK_SPEED_*.

Some numerical (ETH_SPEED_NUM_*) and boolean (ETH_LINK_*) values
are used for the link status (rte_eth_link.*).

There was a mistake in the comment of rte_eth_link.link_autoneg,
suggesting ETH_LINK_SPEED_[AUTONEG/FIXED] which are 0/1,
instead of ETH_LINK_[AUTONEG/FIXED] which are 1/0.

The drivers are fixed to use ETH_LINK_[AUTONEG/FIXED].
