Re: [Xen-devel] [PATCH resend 3/3] 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).

Should you bump this version, or is the comment stale?  The only in-tree consumer I can find is MiniOS's pcifront, which writes it into xenstore.
