Yes, but that's the current behavior for all devices; the patch only
changes it for non-VFs.

VFs could be covered by reading the Command register when the Vendor ID
reads ~0 and waiting while that is ~0, too.  Devices that are ready would
still need only one read.

Lukas, Bjorn: should I do that in v3, or keep the current form?

Thanks,
