This directory is added only for the master -- slaves do not have it. The sysfs iov directory is used to manage and examine the port P_Key and guid paravirtualization. Under iov/ports, the administrator may examine the gid and P_Key tables as they are present in the device (and as are seen in the "network view" presented to the SM). Under the iov/<pci slot number> directories, the admin may map the index numbers in the physical tables (as under iov/ports) to the paravirtualized index numbers that guests see. For example, if the administrator, for port 1 on guest 2 maps physical pkey index 10 to virtual index 1, then that guest, whenever it uses its pkey index 1, will actually be using the real pkey index 10.
