[Xen-devel] [PATCH 6/6] pciif: add multi-vector-MSI command

The requested vector count is to be passed in struct xen_pci_op's info
field. Upon failure, if a smaller vector count might work, the backend
will pass that smaller count in the value field (which so far is always
being set to zero in the error path).
