The dpaa2-eth driver uses in certain circumstances a buffer cache for the S/G tables needed in case of a S/G FD. At the moment, the interraction with the cache is open-coded and couldn't be reused easily. Add two new functions - dpaa2_eth_sgt_get and dpaa2_eth_sgt_recycle - which help with code reusability.

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.
