The ice driver currently attempts to destroy and re-initialize the Tx timestamp tracker during the reset flow. The release of the Tx tracker only happened during CORE reset or GLOBAL reset. The ice_ptp_rebuild() function always calls the ice_ptp_init_tx function which will allocate a new tracker data structure, resulting in memory leaks during PF reset. Certainly the driver should not be allocating a new tracker without removing the old tracker data, as this results in a memory leak. Additionally, there's no reason to remove the tracker memory during a reset. Remove this logic from the reset and rebuild flow. Instead of releasing the Tx tracker, flush outstanding timestamps just before we reset the PHY timestamp block in ice_ptp_cfg_phy_interrupt().

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.
