From 982b1219182ecd5a18a08caaf9be59a8373ac764 Mon Sep 17 00:00:00 2001 From: Anirudh Venkataramanan Date: Thu, 18 Oct 2018 08:37:08 -0700 Subject: ice: Allocate VF interrupts and set queue map Allocate VF interrupts using VPINT_ALLOC_PCI. Multiple interrupts are specified as a range from "first" to "last". Also, according to the spec, the queue mapping for a VF needs to be set in both contig and scatter queue modes. So make this change as well.
