The debugfs code is lazy, and since it only keeps the bottom byte of each connect_info register to save space, it also treats the whole thing as the device_type since the other bits were reserved anyway. Upon closer inspection, though, this is no longer true on newer IP versions, so let's be good and decode the exact field properly. This should help it not get confused when a Component Aggregation Layer is present (which is already implied if Node IDs are found for both device addresses represented by the next two lines of the table).

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.
