Subject: [PATCH] scsi: lpfc: Fix loop mode target discovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The driver does not discover targets when in loop mode.
The NLP type is correctly getting set when a fabric connection is
detected but, not for loop. The unknown NLP type means that the driver
does not issue a PRLI when in loop topology. Thus target discovery
fails.
Fix by checking the topology during discovery. If it is loop, set the
NLP FC4 type to FCP.
