There are still future improvements that could be made: pci-epf-test.c always allocates space for 6 BARs, even when using 64-bit BARs (which really only requires us to allocate 3 BARs). pcitest.sh will print "NOT OKAY" for BAR1, BAR3, and BAR5 when using 64-bit BARs. This could probably be improved to say something like "N/A (64-bit BAR)".
