- 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.
