[ Upstream commit263a425a48] After a number of suspend and resume cycles, it is possible for the RBUF to be stuck in Wake-on-LAN mode, despite the MPD enable bit being cleared which instructed the RBUF to exit that mode. Avoid creating that problematic condition by clearing the RX_EN and TX_EN bits in the UniMAC prior to disable the Magic Packet Detector logic which is guaranteed to make the RBUF exit Wake-on-LAN mode.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
