This commit allows striding RQ to determine MTT page size at runtime, instead of sticking to the compile-time PAGE_SIZE. This functionality will be used by a following commit that adjusts the MTT page size to the XSK frame size. Stick with PAGE_SIZE for XSK on legacy RQ, as frag_stride is not used in data path, it only helps calculate how pages are partitioned into fragments, and PAGE_SIZE will ensure each fragment starts at the beginning of a new allocation unit (XSK frame).

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.
