Until now ack'ing of a new PLOGI has only been delayed if there was an existing session for the same WWN. Ack was released when the session deletion completed. If there was another WWN session with the same fc_id/loop_id pair (aka "conflicting session"), PLOGI was still ack'ed immediately. This potentially caused a problem when old session deletion logged fc_id/loop_id out of FW after new session has been established. Two work-arounds were attempted before: 1. Dropping PLOGIs until conflicting session goes away. 2. Detecting initiator being logged out of FW and issuing LOGO to force re-login. This patch introduces proper solution to the problem where PLOGI is held until either existing session with same WWN or any conflicting session goes away. Mechanism supports one session holding two PLOGI acks as well as one PLOGI ack being held by many sessions.
