commit 43bddb26e20af916249b5318200cfe1734c1700c upstream. If the boot firmware implements connection manager of its own it may not create the paths in the same way or order we do. For example it may create first PCIe tunnel and then USB3 tunnel. When we restore our tunnels (first de-activating them) we may be doing that over completely different tunnels and that leaves them possibly non-functional. For this reason we re-use the tunnel discovery functionality and find out all the existing tunnels, and tear them down. Once that is done we can restore our tunnels.

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.
