We previously did not do this switch because the server didn’t get updates to the MSIx table & PBA. The latest client version (which is not part of this series) forwards accesses to the MSIx table & PBA over to the server. It also reads the PBA set by the server. These change make it possible for the server to make this switch. Thank you! -- Jag > > Stefan
