IB/mlx4: Add iov directory in sysfs under the ib device
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. Based on patch from Erez Shitrit <erezsh@mellanox.com> Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <roland@purestorage.com>
