XSK wakeup flow triggers an IRQ by posting a NOP WQE and hitting the doorbell on the async ICOSQ. It maintains its state so that it doesn't issue another NOP WQE if it has an outstanding one already. For this flow to work properly, the NOP post must not fail. Make sure to reserve room for the NOP WQE in all WQE posts to the async ICOSQ.

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.
