The private structure stored in rte_eth_dev->data->dev_private
was named "struct priv".
In order to ease code browsing, the structure is renamed
"struct mlx[45]_priv".

In some environments it is desirable to have the NIC perform RSS
normally on the packet regardless of the number of queues configured.
The RSS hash result that is stored in the mbuf can then be used by
the application to make decisions about how to distribute workloads
to threads, secondary processes, or even virtual machines if the
application is a virtual switch. This change to the mlx5 driver
aligns with how other drivers in the Intel family work.

This change removes the need to distinguish unlocked priv_*() functions
which are therefore renamed using a mlx5_*() prefix for consistency.
At the same time, all functions from mlx5 uses a pointer to the ETH device
instead of the one to the PMD private data.

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.

Few bugs fixes in both configuration get and hash update where inputs
are not handled as expected by the ethdev layer.
RSS structure may not be totally usable, the PMD should try to take as
most information from it has it can when it is an hash update or it
should try to fill as most as possible in the configuration get.
This means that in the RSS configuration structure, the memory space for
the RSS hash key may not be present, but the PMD should consider the
hash field valid and process/set it.

Reta update needs to stop/start the port but stopping the port does not
disable the polling functions which may end in a segfault if a core is
polling the queue while the control thread is modifying it.
This patch changes the sequences to an order where such situation cannot

Currently mlx5_dev_rss_reta_update() just updates tables in the host,
therefore it isn't immediately effective until restarting the device by
calling mlx5_dev_stop()/mlx5_dev_start() to update the changes in the
device side. This patch adds rebuilding the device-specific data
structure and applying it to the device right away.

ConnectX-4 adapters do not have a constant indirection table size, which is
set at runtime from the number of RX queues. The maximum size is retrieved
using a hardware query and is normally 512.
Since the current RETA API cannot handle a variable size, any query/update
command causes it to be silently updated to RSS_INDIRECTION_TABLE_SIZE
entries regardless of the original size.
Also due to the underlying type of the configuration structure, the maximum
size is limited to RSS_INDIRECTION_TABLE_SIZE (currently 128, at most 256
entries).
A port stop/start must be done to apply the new RETA configuration.

First implementation of rss_hash_update and rss_hash_conf_get, those
functions still lack in functionality but are usable to change the RSS
hash key. For now, the PMD does not handle an indirection table for
each kind of flow (IPv4, IPv6, etc.), the same RSS hash key is used
for all protocols. This situation explains why the rss_hash_conf_get
returns the RSS hash key for all DPDK supported protocols and why the
hash key is set for all of them too.
