We currently read how sibling lane adapter ports relate each other from DROM (Device ROM). If the two lane adapter ports go through the same physical connector these lanes can then be bonded together. However, some cases DROM does not provide this information or it is missing completely (host routers typically do not have DROM). In this case we have hard-coded the relationship. Expand this to work with both legacy devices where lane adapter ports 1 and 2, and 3 and 4 are always linked together, and with USB4 devices where lane adapter 1 is always following lane adapter 0 or is disabled completely (see USB4 section 5.2.1 for more information).

README
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.
