Previously we waited for a whole 15 seconds before we cleared the Tx timestamp state. This is astronomically long compared to the worst case timings expected by our devices. In addition, this is longer than the wait in ptp4l when it detects a fault (caused by missing Tx timestamps). Thus, reduce the timer to only 1 second, which is well after the maximum expected delay. This should reduce user frustration when a timestamp does get dropped for some reason.

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.
