Thanks for the feedback. I'm still wondering though about the usefulness of disabling / enabling SRPT per HCA port. For the use cases I know about SRP communication over all target ports will be enabled as soon as target configuration has finished and more fine-grained access configuration will occur by allowing/disallowing certain initiators to log in.
