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.
