[ Upstream commit e3419e1e44b87d4176fb98679a77301b1ca40f63 ] [WHY] In the worst case, AUX intra-hop done can take hundreds of milliseconds as each retimer in a link might have to wait a full AUX_RD_INTERVAL to send LT abort downstream. [HOW] Wait 300ms for each retimer in a link to allow time to propagate a LT abort without infinitely waiting on intra-hop done. For no-retimer case, keep the max duration at 10ms.

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.
