From 1b6f71f7fcb685970aa1c4ecca3dd60ed37a32ea Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 12 Apr 2022 15:20:04 -0700 Subject: scsi: lpfc: Change FA-PWWN detection methodology Do not rely on vendor version field of the CSPs to determine if we are in a FA-PWWN environment. Instead, use the following procedure: First, during HBA initialization, driver does a READ_CONFIG to determine if FA-PWWN is configured on the HBA. A LPFC_FAWWPN_CONFIG hba_flag is set accordingly. Next, when the link comes up before the driver gets a link up event, the firmware logs into the fabric with FA-PWWN. If the fabric port does not support FA-PWWN, the driver will get a Misconfigured FA-WWN async event before the link up. A LPFC_FAWWPN_FABRIC hba_flag will be set accordingly. Finally, if the fabric supports FA-PWWN, the firmware will replace its CSPs WWN with the Fabric Assigned ones. Then after link up, the driver will retrieve the Fabric Assigned WWN when it does a READ_SPARAM mbox command.

Move setting ELS_ID logic into __lpfc_sli_prep_els_req_rsp_s4(), and remove ELS_ID FIP dependency logic from lpfc_sli_prep_wqe(). Introduce PLOGI ELS_ID and as a result update wqe_els_id_MASK because PLOGI ELS_ID = 0x4 occupies up to 3 bits. While in __lpfc_sli_prep_els_req_rsp_s4() routine, remove SLI3-isms.
