Unlike previous generations, idpf requires more buffer types for optimal performance. This includes: header buffers, short buffers, and no-overhead buffers (w/o headroom and tailroom, for TCP zerocopy when the header split is enabled). Introduce libeth Rx buffer type and calculate page_pool params accordingly. All the HW-related details like buffer alignment are still accounted. For the header buffers, pick 256 bytes as in most places in the kernel (have you ever seen frames with bigger headers?).

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.
