Looking at
pci_match_one_device() it checks both subvendor and subdevice there.
Thanks
But IIUC there is no guarantee that driver with a specific subvendor
matches in presence of a generic one.
So either IFC or virtio pci can win, whichever binds first.
I'm not sure I get there. But I try manually bind IFCVF to qemu's
virtio-net-pci, and it fails.
Thanks
Right but the reverse can happen: virtio-net can bind to IFCVF first.
That's kind of expected. The PF is expected to be bound to virtio-pci to
create VF via sysfs.
Thanks
