Currently the rxe driver has a rxe_mw struct object but nothing about memory windows is enabled. This patch turns on memory windows and some minor cleanup. Set device attribute in rxe.c so max_mw = MAX_MW. Change parameters in rxe_param.h so that MAX_MW is the same as MAX_MR. Reduce the number of MRs and MWs to 4K from 256K. Add device capability bits for 2a and 2b memory windows. Removed RXE_MR_TYPE_MW from the rxe_mr_type enum.

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.
