5Description:	Instructs an SRP initiator to disconnect from a target and to
6		remove all LUNs imported from that target.

12Description:	Number of seconds the SCSI layer will wait after a transport
13		layer error has been observed before removing a target port.
14		Zero means immediate removal. Setting this attribute to "off"
15		will disable the dev_loss timer.

21Description:	Number of seconds the SCSI layer will wait after a transport
22		layer error has been observed before failing I/O. Zero means
23		failing I/O immediately. Setting this attribute to "off" will
24		disable the fast_io_fail timer.

30Description:	16-byte local SRP port identifier in hexadecimal format. An
31		example: 4c:49:4e:55:58:20:56:49:4f:00:00:00:00:00:00:00.

43Description:	State of the transport layer used for communication with the
44		remote port. "running" if the transport layer is operational;
45		"blocked" if a transport layer error has been encountered but
46		the fast_io_fail_tmo timer has not yet fired; "fail-fast"
47		after the fast_io_fail_tmo timer has fired and before the
48		"dev_loss_tmo" timer has fired; "lost" after the
49		"dev_loss_tmo" timer has fired and before the port is finally
50		removed.
