[v3,00/11] add mlx5 compress PMD

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.

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.

v3:
Address Slava and Akhil comments:
	- Maintain alphabetical order in compress driver lists.
	- Improve docs \ commit logs with more information.
	- Fix checkptch warning.
	- Support 32-bit systems.
	- Validate primary procces only working.
	- fix memory leak in error flow of QP creation. 
	- Improve coding style.
	- Improve operation error report in data-path.
rebased code.

v2:
Add documentation.


Matan Azrad (11):
  common/mlx5: add DevX attributes for compress

Send a separate patch for whatever changes you suspect in patch 1/11. I will squash it before the tree is pulled in main branch.

Thanks.
