When the firmware connection manager is not proxying between the software and the hardware we can decrease the timeout for control packets significantly. The USB4 spec recommends 10 ms +- 1 ms but we use slightly larger value (100 ms) which is recommendation from Intel Thunderbolt firmware folks. When firmware connection manager is running then we keep using the existing 5000 ms. To implement this we move the control channel allocation to tb_domain_alloc(), and pass the timeout from that function to the tb_ctl_alloc(). Then make both connection manager implementations pass the timeout when they alloc the domain structure. While there update kernel-doc of struct tb_ctl to match the reality.

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.
