The "tx_db_nc" devarg forces doorbell register mapping to non-cached
region eliminating the extra write memory barrier. This argument was
used in creating the UAR for Tx and thus affected its performance.
Recently [1] its use has been extended to all UAR creation in all mlx5
drivers, and now its name is no longer so accurate.
This patch changes its name to "sq_db_nc" to suit any send queue that
uses it. The old name will still work for backward compatibility.

The sharing device context structure has a field named "devx" which
indicates if DevX is supported.
The common configure structure has also field named "devx" with the same
meaning.
There is no need for this duplication, because there is a reference to

This patch removes it from sharing device context structure and uses the

In the striding RQ management there are two important parameters, the
size of the single stride in bytes and the number of strides.
Both the data-path structure and config structure keep the log of the
above parameters. However, in their names there is no mention that the
value is a log which may be misleading as if the fields represent the
values themselves.
This patch updates their names describing the values more accurately.

The rdma-core library can map doorbell register in two ways, depending
on the environment variable "MLX5_SHUT_UP_BF":
- as regular cached memory, the variable is either missing or set to
zero. This type of mapping may cause the significant doorbell
register writing latency and requires an explicit memory write
barrier to mitigate this issue and prevent write combining.
- as non-cached memory, the variable is present and set to not "0"
value. This type of mapping may cause performance impact under
heavy loading conditions but the explicit write memory barrier is
not required and it may improve core performance.
The UAR creation function maps a doorbell in one of the above ways
according to the system. In run time, it always adds an explicit memory
barrier after writing to.
In cases where the doorbell was mapped as non-cached memory, the
explicit memory barrier is unnecessary and may impair performance.
The commit [1] solved this problem for a Tx queue. In run time, it
checks the mapping type and provides the memory barrier after writing to
a Tx doorbell register if it is needed. The mapping type is extracted
directly from the uar_mmap_offset field in the queue properties.
This patch shares this code between the drivers and extends the above
solution for each of them.

In the past, all the queues and other hardware objects were created
through Verbs interface. Currently, most of the objects creation are
migrated to Devx interface by default, including queues. Only when
the DV is disabled by device arg or eswitch is enabled, all or some
of the objects are created through Verbs interface.
When using Devx interface to create queues, the kernel driver
behavior is different from the case using Verbs. The Tx loopback
cannot work properly even if the Tx and Rx queues are configured
with loopback attribute. To fix the support self loopback for Tx, a
Verbs dummy queue pair needs to be created to trigger the kernel to
enable the global loopback capability.
This is only required when TIR is created for Rx and loopback is
needed. Only CQ and QP are needed for this case, no WQ(RQ) needs to
be created.

The mlx5_rxtx.c file contains a lot of Tx burst functions, each of those
is performance-optimized for the specific set of requested offloads.
These ones are generated on the basis of the template function and it
takes significant time to compile, just due to a large number of giant
functions generated in the same file and this compilation is not being
done in parallel with using multithreading.
Therefore we can split the mlx5_rxtx.c file into several separate files
to allow different functions to be compiled simultaneously.
