Fixing the match table for vdpa/ifcvf driver because as per the Virtio
device specification, drivers MAY match any PCI Subsystem Vendor ID and
any PCI Subsystem Device ID value.

Fixes: a60b747d0ad ("vdpa/ifc: support virtio block device")
Fixes: 5c806b94785 ("vdpa/ifc: add PCI ID for legacy network device")

Hi Abhishek,

Please see comments inline.

Here the "drivers" refers to virtio driver, not vdpa driver.
With below change, this vdpa/ifc driver would hit the standard virtio device which can't 100% match this driver.

Hi Abhishek,

I agree with Xiao.
I think it will be better you just add subvendor and subdevice you want to be take care of by this vdpa driver.

Is that really a fix? If so, you need to add the Fixes tag so that LTS
