Back when the libeth Rx core was initially written, devmem was a draft and netmem_ref didn't exist in the mainline. Now that it's here, make libeth MP-agnostic before introducing any new code or any new library users. When it's known that the created PP/FQ is for header buffers, use faster "unsafe" underscored netmem <--> virt accessors as netmem_is_net_iov() is always false in that case, but consumes some cycles (bit test + true branch).

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.
