This patch refactors aspects of the VSI allocation, deletion and rebuild flow. Some of the more noteworthy changes are described below. 1) On reset, all switch filters applied in the hardware are lost. In the rebuild flow, only MAC and broadcast filters are being restored. Instead, use a new function ice_replay_all_fltr to restore all the filters that were previously added. To do this, remove calls to ice_remove_vsi_fltr to prevent cleaning out the internal bookkeeping structures that ice_replay_all_fltr uses to replay filters. 2) Introduce a new state bit __ICE_PREPARED_FOR_RESET to distinguish the PF that requested the reset (and consequently prepared for it) from the rest of the PFs. These other PFs will prepare for reset only when they receive an interrupt from the firmware. 3) Use new functions ice_add_vsi and ice_free_vsi to create and destroy VSIs respectively. These functions accept a handle to uniquely identify a VSI. This same handle is required to rebuild the VSI post reset. To prevent confusion, the existing ice_vsi_add was renamed to ice_vsi_init. 4) Enhance ice_vsi_setup for the upcoming SR-IOV changes and expose a new wrapper function ice_pf_vsi_setup to create PF VSIs. Rework the error handling path in ice_setup_pf_sw. 5) Introduce a new function ice_vsi_release_all to release all PF VSIs.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
