/*
* Returns Physical function given a virtual function
/**
* virPCIGetPhysicalFunction:
* @vf_sysfs_path: sysfs path for the virtual function
* @pf: where to store the physical function's address
*
* Given @vf_sysfs_path, this function will store the pointer
* to a newly-allocated virPCIDeviceAddress in @pf.
*
* @pf might be NULL if @vf_sysfs_path does not point to a
* virtual function. If it's not NULL, then it should be
* freed by the caller when no longer needed.
*
* Returns: >=0 on success, <0 on failure
