Update the PFVF logic to handle restart and recovery. This adds the
following functions:
* adf_pf2vf_notify_fatal_error(): allows the PF to notify VFs that the
device detected a fatal error and requires a reset. This sends to
VF the event `ADF_PF2VF_MSGTYPE_FATAL_ERROR`.
* adf_pf2vf_wait_for_restarting_complete(): allows the PF to wait for
`ADF_VF2PF_MSGTYPE_RESTARTING_COMPLETE` events from active VFs
before proceeding with a reset.
* adf_pf2vf_notify_restarted(): enables the PF to notify VFs with
an `ADF_PF2VF_MSGTYPE_RESTARTED` event after recovery, indicating that
the device is back to normal. This prompts VF drivers switch back to
use the accelerator for workload processing.
These changes improve the communication and synchronization between PF
and VF drivers during system restart and recovery processes.

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.
