Currently, rq->mkey_be keeps a big-endian value of either the PA MKey (for legacy RQ, no address translation) or MTT MKey (for striding RQ, direct address translation). Striding RQ stores the same value in rq->umr_mkey in the native endianness. The next commit will make striding RQ use KSM MKey (indirect address translation) for the unaligned mode of XSK, which will require storing both KSM MKey and PA MKey in the RQ struct. This commit optimizes fields of mlx5e_rq: umr_mkey is removed (it's redundant), mkey_be always points to the PA MKey, and mpwqe.umr_mkey_be points to the MTT MKey (or to the KSM MKey, starting from the next commit).

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.
