> The mlx5 compress PMD uses HW acceleration for the compress operations.
> The mlx5 HW device has no level style mode, which does a tradeoff between
> throughput and compression ratio, unlike SW drivers where the CPU is doing

> The mlx5 driver wrongly defined the Huffman block size configuration
> according to the level that doesn't fill the level API requirement for

> Remove the effect of the level configuration in compress operation.
> Add "log-block-size" devarg to select compression block size manually.
