[libvirt] [PATCH v1 08/10] virpcimock: Mock the SRIOV Virtual functions
Daniel Henrique Barboza

Wed Jun 26 19:35:57 UTC 2019
From: Shivaprasad G Bhat <sbhat at linux.vnet.ibm.com>
The softlink to physfn is the way to know if the device is
VF or not. So, the patch softlinks 'physfn' to the parent function.
The multifunction PCI devices dont have 'physfn' softlinks.
The patch adds few Virtual functions to the mock environment and
changes the existing VFIO test xmls using the VFs to use the newly
added VFs for their use case.
