From: Shivaprasad G Bhat <sbhat@xxxxxxxxxxxxxxxxxx>
There are already good number of test cases with hostdevices,
few have multifunction devices but none having more than one
than one multifunction cards.
This patch adds a case where there are two multifunction cards
and two Virtual functions part of the same XML.
0001:01:00.X & 0005:09:00.X - are Multifunction PCI cards.
0000:06:12.[5|6] - are SRIOV Virtual functions
Future commits will improve on automatically detecting the
multifunction cards and auto-assinging the addresses
appropriately.
