This change include several changes as listed below all related to UAR. UAR is a special PCI memory area where the so-called doorbell register and blue flame register live. Blue flame is a feature for sending small packets more efficiently via a PCI memory page, instead of using PCI DMA. - All structures and functions named xxx_uuars were renamed into xxx_bfreg. - Remove partially implemented Blueflame support from mlx5en(4) and mlx5ib. - Implement blue flame register allocator. - Use blue flame register allocator in mlx5ib. - A common UAR page is now allocated by the core to support doorbell register writes for all of mlx5en and mlx5ib, instead of allocating one UAR per sendqueue. - Add support for DEVX query UAR. - Add support for 4K UAR for libmlx5.
