'PF number' was vague and source of confusion. Some started thinking that it is some kind of index like how VF number is an index.
So 'PF number' is rewritten to bring the clarity that it's the function number of the PCI device which is very will described in the PCI spec.

For VF number, the description is added describing it's an index starting from 0 (unlike pci spec where vf number starts from 1).
SF number is user supplied number so nothing to remove there.
