The DWMBB Vector is transmitted to the XMI node that issued
an IDENT when the DWMBB has a pending interrupt request
that matches the interrupt source and IPL sent during the XMI
IDENT transaction. This vector is NOT sent for any VAXBI-generated
interrupts or BIIC interrupts due to error conditions.
