Currently, all HW supporting idpf supports the singleq model, but none of it advertises it by default, as splitq is supported and preferred for multiple reasons. Still, this almost dead code often times adds hotpath branches and redundant cacheline accesses. While it can't currently be removed, add CONFIG_IDPF_SINGLEQ and build the singleq code only when it's enabled manually. This corresponds to -10 Kb of object code size and a good bunch of hotpath checks. idpf_is_queue_model_split() works as a gate and compiles out to `true` when the config option is disabled.

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 reStructuredText 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.
