I run basic checks to the patchset:

There are various checkpatch warnings, all are warning or check level

Patch 8 and 13 failed to apply with via git, -looks line line numbers
shifted a little, this is not a problem since eventually it applies but
just for your information.

check-git-log is giving following errors, it is mainly case issue in Rx/Tx:
Wrong headline lowercase:
        mlx5: resurrect RX scatter support
        mlx5: make RX queue reinitialization safer
        mlx5: remove redundant RX queue initialization code
        mlx5: resurrect TX gather support
        mlx5: check remaining space while processing TX burst
        mlx5: add debugging information about TX queues capabilities
        mlx5: replace countdown with threshold for TX completions
        mlx5: handle RX CQE compression
        mlx5: refactor RX data path
        mlx5: add TX/RX burst function selection wrapper
        mlx5: split RX queue structure
        mlx5: split TX queue structure
        mlx5: remove inline TX support
        mlx5: remove RX scatter support
        mlx5: remove TX gather support
Headline too long:
        mlx5: remove configuration variable for maximum number of segments
        mlx5: split memory registration function for better performance


It compiles fine.
