From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
This patch converts ib_srpt to use srpt_port->port_guid subnet_prefix +
interface_id formatting in srpt_add_one() to identify individual HW
target ports in /sys/kernel/config/target/srpt/$SRPT_WWPN
This layout for SRP Target WWPNs and explict SRP Initiator Node WWPNs
will now appear as:
/ib_srpt> ls
o- ib_srpt ......................................................... [2 Targets]
o- 0xfe800000000000000002c903000e8acd .............................. [enabled]
| o- acls ............................................................ [1 ACL]
| | o- 0x00000000000000000002c903000e8be9 .................... [1 Mapped LUNs]
| | o- mapped_lun0 ............................................. [lun0 (rw)]
| o- luns ........................................................... [1 LUNs]
| o- lun0 ................................... [iblock/scsi_debug (/dev/sdb)]
