[PATCH rdma-next 0/3] Dump and fill MKEY

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@mellanox.com>

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.

Thanks
