The downside to it is a Port Login * may be disrupted (if a PLOGI wasn't actually needed) and another ULP (that * has nothing to do with the PRLO) may be impacted. However, this is a * scenario very unlikely to happen. As of today the only ULP in Leadville * using PRLI/PRLOs is FCP. For a PRLO to disrupt another ULP (that would be * FCIP), a SCSI target would have to be running FCP and FCIP (which is very * unlikely). */ static void fp_handle_unsol_prlo(fc_local_port_t *port, fc_unsol_buf_t *buf, fc_remote_port_t *pd, job_request_t *job) { int busy; int rval; int retain; fp_cmd_t *cmd; fc_portmap_t *listptr; boolean_t tolerance; la_els_prlo_t *req; req = (la_els_prlo_t *)buf->ub_buffer; if ((ntohs(req->payload_length) != (sizeof (service_parameter_page_t) + sizeof (ls_code_t))) || (req->page_length != sizeof (service_parameter_page_t))) { /* * We are being very restrictive.
