This is a revised patch to add an attribute for the port_name of
the physical port.
Regards,

fc transport: add permanent_port_name fc_host attribute
Add fc_host attribute permanent_port_name which is
used to show the port name of the primary port -
the port that initially logged into the fabric.
For a virtual port (registered via the primary port with
FDISC command) it is useful to know not only its (virtual)
port name but also the permanent port name.
