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". Changes in v2: - Rebased patchset on top of dpdk/master. - Fixed CQE size on Power8. - Fixed mbuf assertion failure in debug mode. - Fixed missing class_id field in rte_pci_id by using RTE_PCI_DEVICE.
