[PATCH 00/12] PF: Improve VF control

[Michal Wajdeczko <michal.wajdeczko@intel.com>]

Our initial VF control implementation was focused on providing
a very minimal support for the VF_STATE_NOTIFY events just to
meet GuC requirements, without tracking a VF state or doing any
expected actions (like cleanup in case of the FLR notification).
