This patch removes the internal rx page_cache and uses the generic page_pool api only. It used to be that the page_pool couldn't handle all the mlx5 driver usecases, but with the introduction of skb recycling and page fragmentaton in the page_pool full switch can now be made. Some benfits of this transition: * Better page recycling in the cases when the page_cache was suffering from head of queue blocking. The page_pool doesn't have this issue. * DMA mapping/unmapping can be managed by the page_pool. * mlx5e_rq size reduced by more than 50% due to the page_cache array being deleted. This patch only removes the page_cache. Downstream patches will enable the required page_pool features and will add further fine-tuning.

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.
