The current design of mlx5e driver ignores the netdevice TX/RX queues
number for netdevices that RDMA IPoIB ULP creates. Instead, the queue
number is initialized to the maximum number that mlx5 thinks best for
performance. As a result, ULP drivers that choose to create a netdevice
with queue number that is less than the maximum channels mlx5 creates,
will get a memory corruption.
This fix changes the mlx5e netdev logic to respect ULP netdevices TX/RX
queue number and use it when creating resources instead of the maximum
channel number.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
