There is a lot of code in taprio which is "borrowed" from mqprio. It makes sense to put a stop to the "borrowing" and start actually reusing code. Because taprio and mqprio are built as part of different kernel modules, code reuse can only take place either by writing it as static inline (limiting), putting it in sch_generic.o (not generic enough), or creating a third auto-selectable kernel module which only holds library code. I opted for the third variant. In a previous change, mqprio gained support for reverse TC:TXQ mappings, something which taprio still denies. Make taprio use the same validation logic so that it supports this configuration as well. The taprio code didn't enforce TXQ overlaps in txtime-assist mode and that looks intentional, even if I've no idea why that might be. Preserve that, but add a comment. There isn't any dedicated MAINTAINERS entry for mqprio, so nothing to update there.

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.
