ctx_q_num is a module parameter set by the user to specify the number of qp queues required to create a ctx. When the number of qp queues allocated by PF or VF is less than the ctx_q_num, an error will be reported when ctx is initialized in kernel mode, which leads to the problem that the registered algorithms cannot be used. Therefore, when PF or VF is initialized, if the number of qp queues is not enough to create a ctx, the kernel mode cannot be used, and there is no need to register the kernel mode algorithms.

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.
