In the case when the driver is running in target mode, the topology is N2N and the target port has higher WWPN, LOCAL_LOOP_UPDATE bit is cleared too early and PLOGI payload is not initialized by the Get Parameters command. That causes a failure of ELS IOCB carrying the PLOGI with 0x15 aka Data Underrun error. LOCAL_LOOP_UPDATE has to be set to initialize PLOGI payload.
