[ Upstream commit 5fd6b9a5cbe63fea4c490fee8af34144a139a266 ] In case of uni-directional time sync, TMU handshake is initiated by upstream router. In case of bi-directional time sync, TMU handshake is initiated by downstream router. In order to handle correctly the case of uni-directional mode, we avoid changing the upstream router's rate to off, because it might have another downstream router plugged that is set to uni-directional mode (and we don't want to change its mode). Instead, we always change downstream router's rate.

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.
