Running "./devtools/check-meson.py --fix" on the DPDK repo fixes a
number of issues with whitespace and formatting of files:
* indentation of lists
* missing trailing commas on final list element
* multiple list entries per line when list is not all single-line

This patch adds support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.1000
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for newly
added fields cause the queue creation to fail.
The patch queries the timestamp formats supported by the hardware
and sets the configuration values in queue context accordingly.

In order to support 32-bit systems, the 8B doorbell write should be
done by 2 4B stores.
The order between the store is important, that's why memory barrier
should be used between them.
The doorbell address is shared between all the queues, that's why a lock
should wrap the 2 stores.

Add implementation for the next compress data-path functions:
- dequeue_burst
- enqueue_burst
Add the next operation for starting \ stopping data-path:
- dev_stop
- dev_close
Each compress API enqueued operation is translated to a WQE.
Once WQE is done, the HW sends CQE to the CQ, when SW see the CQE the
operation will be updated and dequeued.

Mellanox user space drivers don't deal with physical addresses, that's
why any mbuf virtual address moved directly to the HW descriptor(WQE).
The mapping between the virtual address to the physical address is saved
in MR configured by the kernel to the HW.
Each MR has a key that should also be moved to the WQE by the SW.
When the SW see address which is not mapped, it extends the address
range and creates a MR using a system call.
Add memory region cache management:
- 2 level cache per queue-pair - no locks.
- 1 shared cache between all the queues using a lock.
Using this way, the MR key search per data-path address is optimized.

Add a new compress PMD for Mellanox devices.
The MLX5 compress driver library provides support for Mellanox
BlueField 2 families of 25/50/100/200 Gb/s adapters.
GGAs (Generic Global Accelerators) are offload engines that can be used
to do memory to memory tasks on data.
These engines are part of the ARM complex of the BlueField 2 chip, and
as such they do not use NIC related resources (e.g. RX/TX bandwidth).
They do share the same PCI and memory bandwidth.
So, using the BlueField 2 device, the compress class operations can be
run in parallel to the net, vdpa, and regex class operations.
This driver is depending on rdma-core like the other mlx5 PMDs, also it
is going to use mlx5 DevX to create HW objects directly by the FW.
Add the probing functions, PCI bus connectivity, HW capabilities checks
and some basic objects preparations.
