The USB4 Connection Manager guide provides detailed information how the USB4 router buffer (credit) allocation information should be used by the connection manager when it allocates buffers for different paths. This patch implements it for Linux. For USB 3.x and DisplayPort we use directly the router preferences. The rest of the buffer space is then used for PCIe and DMA (peer-to-peer, XDomain) traffic. DMA tunnels require at least one buffer and PCIe six, so if there is not enough buffers we fail the tunnel creation. For the legacy Thunderbolt 1-3 devices we use the existing hard-coded scheme except for DMA where we use the values suggested by the USB4 spec chapter 13.

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.
