Subject: [net-next 04/15] ice: Update VSI and queue management code to handle VF VSI
From: Anirudh Venkataramanan <anirudh.venkataramanan@...el.com>
Until now, all the VSI and queue management code supported only the PF
VSI type (ICE_VSI_PF). Update these flows to handle the VF VSI type
(ICE_VSI_VF) type as well.
