From f8e9889f54da6e3146c2cb3f5c206cf1a704f9d3 Mon Sep 17 00:00:00 2001 From: Michal Swiatkowski Date: Tue, 24 Oct 2023 16:20:10 +0200 Subject: ice: change vfs.num_msix_per to vf->num_msix vfs::num_msix_per should be only used as default value for vf->num_msix. For other use cases vf->num_msix should be used, as VF can have different MSI-X amount values. Fix incorrect register index calculation. vfs::num_msix_per and pf->sriov_base_vector shouldn't be used after implementation of changing MSI-X amount on VFs. Instead vf->first_vector_idx should be used, as it is storing value for first irq index.
