From: Wei Yang <weiy...@linux.vnet.ibm.com>
When we size VF BAR0, VF BAR1, etc., from the SR-IOV Capability of a PF, we
learn the alignment requirement and amount of space consumed by a single
VF. But when VFs are enabled, *each* of the NumVFs consumes that amount of
space, so the total size of the PF resource is "VF BAR size * NumVFs".
Add a printk of the total space consumed by the VFs corresponding to what
we already do for normal non-IOV BARs.
No functional change; new message only.
[bhelgaas: split out into its own patch]
