According to Bspec #20124, max link rate table for DP was updated at BDB version 230. Max link rate can support upto UHBR. After migrate to BDB v230, the definition for LBR, HBR2 and HBR3 were changed. For backward compatibility. If BDB version was from 216 to 229. Driver have to follow original rule to configure DP max link rate value from VBT. v2: split the mapping table to two for old and new BDB definition. v3: return link rate instead of assigning it. v4: remove the useless variable.

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.
