be2net: fix vfs enumeration
Current VFs enumeration algorithm used in be_find_vfs does not take domain number into the match. The match found in igb/ixgbe is more elegant and safe. This 2nd version uses pci_physfn instead of checking dev->physfn directly. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
