From: Shivaprasad G Bhat <sbhat(a)linux.vnet.ibm.com>
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
The next few commits improve on automatically detecting the multifunction
cards and auto-assinging the addresses appropriately.
