take the proper actions to bring the associated pci_devinst (which
from the guest’s perspective isn’t a discrete element) back to it’s
reset state too.
Hi,

vc_reset. Typically this means a call to vi_reset_dev() which resets a
bunch of fields in virtio_softc, but does not touch a corresponding
pci_devinst (hanging off vs_pi) at all. Among other things this means
that PCI MSI an
