[ Upstream commit 59f1622a5f05d948a7c665a458a3dd76ba73015e ]
[Why]
If bandwidth allocation feature is enabled, connection manager wont
limit the dp tunnel bandwidth. So, need to do display mode validation
for streams on dpia links to avoid oversubscription of dp tunnel
bandwidth.
[How]
- To read non reduced link rate and lane count and update
reported link capability.
- To calculate the bandwidth required for streams of dpia links
per host router and validate against the allocated bandwidth for
the host router.

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.
