Enhance mlx5 with a data path that bypasses Verbs. The first half of this patchset removes support for functionality completely rewritten in the second half (scatter/gather, inline send), while the data path is refactored without Verbs.
The PMD remains usable during the transition. This patchset must be applied after "Miscellaneous fixes for mlx4 and mlx5".
