Linux kernel source tree

The ice_ptp_prepare_for_reset() and ice_ptp_reset() functions currently check the pf->flags ICE_FLAG_PFR_REQ bit to determine if the current reset is a PF reset or not. This is problematic, because it is possible that a PF reset and a higher level reset (CORE reset, GLOBAL reset, EMP reset) are requested simultaneously. In that case, the driver performs the highest level reset requested. However, the ICE_FLAG_PFR_REQ flag will still be set. The main driver reset functions take an enum ice_reset_req indicating which reset is actually being performed. Pass this data into the PTP functions and rely on this instead of relying on the driver flags. This ensures that the PTP code performs the proper level of reset that the driver is actually undergoing.

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.
