Initial series ading packed ring layout support to the vhost library was missing the save and restore of the wrap counters and indexs on vring base requests used for migration. First patch saves/restores the used and avail indexes and their wrap counters values into/from the vring state num field. Patch 2 advertise support for the packed ring.
