Pull Dump and fill MKEY from Leon Romanovsky:

====================
MLX5 IB HCA offers the memory key, dump_fill_mkey to increase performance,
when used in a send or receive operations.

It is used to force local HCA operations to skip the PCI bus access, while
keeping track of the processed length in the ibv_sge handling.

In this three patch series, we expose various bits in our HW spec
file (mlx5_ifc.h), move unneeded for mlx5_core FW command and export such
memory key to user space thought our mlx5-abi header file.
====================

Botched auto-merge in mlx5_ib_alloc_ucontext() resolved by hand.

* branch 'mlx5-dump-fill-mkey':
  IB/mlx5: Expose dump and fill memory key
  net/mlx5: Add hardware definitions for dump_fill_mkey
  net/mlx5: Limit scope of dump_fill_mkey function
  net/mlx5: Rate limit errors in command interface
