Session names
-------------
The name assigned by the ib_srpt target driver to a session depends on the
mode in which it is operating. If one_target_per_port=y then the source port
GID is used as the session name. If one_target_per_port=n then the 128-bit SRP
initiator port identifier is used as the session name. This identifier is sent
by the SRP initiator to the SRP target via the SRP_LOGIN_REQ information unit.
The Linux SRP initiator (ib_srp) generates the initiator port identifier as
follows:
- The first eight bytes are the identifier extension ('initiator_ext' parameter
specified in the login string echoed into the sysfs file 'add_target').
- The last eight bytes are the GUID of the initiator HCA port used to
communicate with the target.
The ib_srpt target driver uses the source port GID as session name.
