Maor Gottlieb 5f87d4dc58 RDMA/mlx5: Fix validation of max_rd_atomic caps for DC
[ Upstream commit 8de8482fe5732fbef4f5af82bc0c0362c804cd1f ]

Currently, when modifying DC, we validate max_rd_atomic user attribute
against the RC cap, validate against DC. RC and DC QP types have different
device limitations.

This can cause userspace created DC QPs to malfunction.

Fixes: c32a4f296e ("IB/mlx5: Add support for DC Initiator QP")

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.
