Lior Nahmanson 11656f593a RDMA/mlx5: Add DCS offload support
DCS is an offload to SW load balancing of DC initiator work requests.

A single DCI can be connected to only one target at the time and can't
start new connection until the previous work request is completed.  This
limitation will cause to delay when the initiator process needs to
transfer data to multiple targets at the same time.  The SW solution is to
use a process that handling and spreading the work request on many DCIs
according to destinations.

This feature is an offload to this process and coming to reduce the load
from the CPU and improve the performance.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
