Usual collection of driver changes, more core infrastructure updates that
typical this cycle:
- Minor cleanups and kernel-doc fixes in bnxt_re, hns, rdmavt, efa, ocrdma,
erdma, rtrs, hfi1, ionic, and pvrdma
- New udata validation framework and driver updates
- Modernize CQ creation interface in mlx4 and mlx5, manage CQ umem in core
- Promote UMEM to a core component, split out DMA block iterator logic
- Introduce FRMR pools with aging, statistics, pinned handles, and netlink
control and use it in mlx5
- Add PCIe TLP emulation support in mlx5
- Extend umem to work with revocable pinned dmabuf's and use it in irdma
- More net namespace improvements for rxe
- GEN4 hardware support in irdma
- First steps to MW and UC support in mana_ib
- Support for CQ umem and doorbells in bnxt_re
- Drop opa_vnic driver from hfi1
- Fixes:
IB/core zero dmac neighbor resolution race
GID table memory free
rxe pad/ICRC validation and r_key async errors
mlx4 external umem for CQ
umem DMA attributes on unmap
mana_ib RX steering on RSS QP destroy
