In PTP Tx implementation, driver kept scheduling a poll thread until the timestamp is available. In the error scenarios (e.g. app requesting the timestamp for non-ptp packet), this thread kept waiting for the timestamp forever. This patch add changes to report such scenario as an error and terminate the thread. Added a timeout of 2 seconds i.e., max time to wait for Tx timestamp. Added a stat value ptp_skip_txts for reporting the number of packets for which Tx timestamping is skipped.

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.
