There is a naming convention for logtypes of PMDs:
"pmd.driverType.driverName".
Therefore, the logtype for ISA-L PMD should be "pmd.compress.isal".

This patch adds support for an additional bus type Virtual Machine BUS
(VMBUS) on Microsoft Hyper-V in Windows 10, Windows Server 2016
and Azure. Most of this code was extracted from FreeBSD and some of
this is from earlier code donated by Brocade.
Only Linux is supported at present, but the code is split
to allow future FreeBSD and Windows support.
The bus support relies on the uio_hv_generic driver from Linux
kernel 4.16. Multiple queue support requires additional sysfs
interfaces which is in kernel 5.0 (a.k.a 4.17).

This patch adds support for building and running mlx5 PMD on
32bit systems such as i686.
The main issue to tackle was handling the 32bit access to the UAR
as quoted from the mlx5 PRM:
QP and CQ DoorBells require 64-bit writes. For best performance, it
is recommended to execute the QP/CQ DoorBell as a single 64-bit write
operation. For platforms that do not support 64 bit writes, it is
possible to issue the 64 bits DoorBells through two consecutive
writes,
each write 32 bits, as described below:
* The order of writing each of the Dwords is from lower to upper
addresses.
* No other DoorBell can be rung (or even start ringing) in the midst
of an on-going write of a DoorBell over a given UAR page.
The last rule implies that in a multi-threaded environment, the access
to a UAR page (which can be accessible by all threads in the process)
must be synchronized (for example, using a semaphore) unless an atomic
write of 64 bits in a single bus operation is guaranteed. Such a
synchronization is not required for when ringing DoorBells on different
UAR pages.

The flow counter support introduced by
commit 9a761de8ea14 ("net/mlx5: flow counter support") was intend to
work only with MLNX_OFED_4.3 as the upstream rdma-core
libraries were lack such support.
On rdma-core v19 the support for the flow counters was added but with
different user APIs, hence causing compilation issues on the PMD.
This patch fix the compilation errors by forcing the flow counters
to be enabled only with MLNX_OFED APIs.
Once MLNX_OFED and rdma-core APIs will be aligned, a proper patch to
support the new API will be submitted.

The current PCI probing method is not aware of Verbs port representors,
which appear as standard Verbs devices bound to the same PCI address and
cannot be distinguished.
Problem is that more often than not, the wrong Verbs device is used,
resulting in unexpected traffic.
This patch makes the driver discard representors to only use the master
device. If unable to identify it (e.g. kernel drivers not recent enough),
either:
- There is only one matching device which isn't identified as a
representor, in that case use it.
- Otherwise log an error and do not probe the device.
