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.
