Hwqueue has collect statistics in heavy use queue_pop/queu_push functions for cache efficiency and make push/pop faster use percpu variables. For performance reasons, driver should keep descriptor in software handler as short as possible and quickly return it back to hardware queue. Descriptors coming into driver from hardware after pop and return back by push to reduce descriptor lifetime in driver collect statistics on percpu.

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.
