[SCSI] add srp transport class This adds srp transport class that works with ib_srp and ibmvscsi. It creates only /sys/class/{srp_host,srp_remote_ports} and srp_remote_ports has only "port_id" attribute. viola:/sys/class/srp_remote_ports/port-0:1# ls device port_id subsystem uevent viola:/sys/class/srp_remote_ports/port-0:1# cat port_id 4c:49:4e:55:58:20:56:49:4f:00:00:00:00:00:00:00 Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

[SCSI] transport_srp: add rport roles attribute This adds a 'roles' attribute to rport like transport_fc. The role can be initiator or target. That is, the initiator driver creates target remote ports and the target driver creates initiator remote ports.
