[ Upstream commit 4a48ef70b93b8c7ed5190adfca18849e76387b80 ] The functions that register an XDP memory model take a struct xdp_rxq as parameter, but the RXQ is not actually used for anything other than pulling out the struct xdp_mem_info that it embeds. So refactor the register functions and export variants that just take a pointer to the xdp_mem_info. This is in preparation for enabling XDP_REDIRECT in bpf_prog_run(), using a page_pool instance that is not connected to any network device.

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.
