Currently VF VSI are being reset twice during a PFR or greater. This is causing reset, specifically resetting all VFs, to take too long. This is causing various issues with VF drivers not being able to gracefully handle the VF reset timeout. Fix this by refactoring how VF reset is handled for the case mentioned previously and for the VFR/VFLR case. The refactor was done by doing the following: 1. Removing the call to ice_vsi_rebuild_by_type for ICE_VSI_VF VSI, which was causing the initial VSI rebuild. 2. Adding functions for pre/post VSI rebuild functions that can be called in both the reset all VFs case and reset individual VF case. 3. Adding VSI rebuild functions that are specific for the reset all VFs case and adding functions that are specific for the reset individual VF case. 4. Calling the pre-rebuild function, then the specific VSI rebuild function based on the reset type, and then calling the post-rebuild function to handle VF resets. This patch series makes some assumptions about how VSI are handling by FW during reset: 1. During a PFR or greater all VSI in FW will be cleared. 2. During a VFR/VFLR the VSI rebuild responsibility is in the hands of the PF software. 3. There is code in the ice_reset_all_vfs() case to amortize operations if possible. This was left intact. 4. PF software should not be replaying VSI based filters that were added other than host configured, PF software configured, or the VF's default/LAA MAC. This is the VF drivers job after it has been reset.
