ICOSQ is used to post UMR WQEs for both regular RQ and XSK RQ. However,
space in ICOSQ is reserved only for the regular RQ, which may cause
ICOSQ overflows when using XSK (the most risk is on activating
channels).
This commit fixes the issue by reserving space for XSK UMR WQEs as well.
As XSK may be enabled without restarting the channel and recreating the
ICOSQ, this space is reserved unconditionally.

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.
