Instead of allocating page fragments via the network stack, use the page allocator directly. For now, we consume one page for each Rx buffer. With the new memory model we are free to consider adding more XDP support. Performance decreases slightly in some IP forwarding cases. No visible effect on termination traffic. The driver memory footprint increases as a result of this change, but it is still small enough to not really matter. Another side effect is that now Rx buffer alignment requirements are naturally satisfied without any additional actions needed. Remove alignment related code, except in the buffer layout information conveyed to MC, as hardware still needs to know the alignment value we guarantee.

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.
