Add 'idle_poll_period_usecs' option used by io_work() to support network devices enabled with advanced interrupt moderation supporting a relaxed interrupt model. It was discovered that such a NIC used on the target was unable to support initiator connection establishment, caused by the existing io_work() flow that immediately exits after a loop with no activity and does not re-queue itself. With this new option a queue is assigned a period of time that no activity must occur in order to become 'idle'. Until the queue is idle the work item is requeued. The new module option is defined as changeable making it flexible for testing purposes. The pre-existing legacy behavior is preserved when no module option for idle_poll_period_usecs is specified.

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.
