The current implementation uses the workqueue for peripheral chips to submit work. Only a single work item is queued and used at any time. To be able to keep more than one transmit in flight at a time, prepare the workqueue to support multiple transmits at the same time. Each work item now has a separate storage for a skb and a pointer to cdev. This assures that each workitem can be processed individually. The workqueue is replaced by an ordered workqueue which makes sure that only a single worker processes the items queued on the workqueue. Also items are ordered by the order they were enqueued. This removes most of the concurrency the workqueue normally offers. It is not necessary for this driver. The cleanup functions have to be adopted a bit to handle this new mechanism.

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.
