[SCSI] zfcp: transport class adaptations II
Replaced zfcp adapter attributes with fc_host attributes: fc_topology by port_type, physical_wwpn by permanent_port_name. Make use of fc_host attribute supported_speeds. Removed zfcp adapter attribute physical_s_id. Signed-off-by: Andreas Herrmann <aherrman@de.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
