2018-08-02scsi: qla2xxx: Migrate NVME N2N handling into state machineQuinn Tran1-0/+5
This patch fixes regression introduced for the N2N support for FC-NVMe. For FC-NVMe with N2N connection, instead of FW initiating the Login, Driver starts Login process. This patch migrates that new process from a standalone path into existing session management state machine. With this state change now driver will not wait for pull NPort ID from FW.

2018-01-03scsi: qla2xxx: Fix session cleanup for N2NQuinn Tran1-1/+1
When connection type is N_Port to N_Port (point-to-point), there is a possibilty where initiator will not send PLOGI request and will directly send PRLI. In N2N connection the port has higher port name sends the PLOGI but not allow to send PRLI if is a target mode. Only initiator is allowed to send PRLI. Current driver code deletes old session when it receives PLOGI request. If we will not receive PLOGI request then we will not delete old session and create new session. Add check for N2N with PRLI receive only and trigger cleanup. For this case, the cleanup requires individual cmd abort instead of using implicit logout as a broad stroke flush.

2017-06-27scsi: qla2xxx: Add FC-NVMe port discovery and PRLI handlingDuane Grigsby1-1/+12
Added logic to change the login process into an optional PRIL step for FC-NVMe ports as a separate operation, such that we can change type to 0x28 (NVMe). Currently, the driver performs the PLOGI/PRLI together as one operation, but if the discovered port is an NVMe port then we first issue the PLOGI and then we issue the PRLI. Also, the fabric discovery logic was changed to mark each discovered FC NVMe port, so that we can register them with the FC-NVMe transport later.

2017-02-09qla2xxx: Improve RSCN handling in driverQuinn Tran1-13/+62
Current code blindly does State Change Registration when the link is up. Move SCR behind fabric scan, so that arbitrated loop scan would not get erroneous error message. Some of the other improvements are as follows - Add session deletion for TPRLO and send acknowledgment for TPRLO. - Enable FW option to move ABTS, RIDA & PUREX from RSPQ to ATIOQ. - Save NPort ID early in link init. - Move ABTS & RIDA to ATIOQ helps in keeping command ordering and link up sequence ordering. - Save Nport ID and update VP map so that SCSI CMD/ATIO won't be dropped. - fcport alloc does the initializes memory to zero. Remove memset to zero since It might corrupt link list. - Turn off Registration for State Change MB in loop mode.

2017-02-09qla2xxx: Add framework for async fabric discoveryQuinn Tran1-0/+31
Currently code performs a full scan of the fabric for every RSCN. Its an expensive process in a noisy large SAN. This patch optimizes expensive fabric discovery process by scanning switch for the affected port when RSCN is received. Currently Initiator Mode code makes login/logout decision without knowledge of target mode. This causes driver and firmware to go out-of-sync. This framework synchronizes both initiator mode personality and target mode personality in making login/logout decision. This patch adds following capabilities in the driver - Send Notification Acknowledgement asynchronously. - Update session/fcport state asynchronously. - Create a session or fcport struct asynchronously. - Send GNL asynchronously. The command will ask FW to provide a list of FC Port entries FW knows about. - Send GPDB asynchronously. The command will ask FW to provide detail data of an FC Port FW knows about or perform ADISC to verify the state of the session. - Send GPNID asynchronously. The command will ask switch to provide WWPN for provided NPort ID. - Send GPSC asynchronously. The command will ask switch to provide registered port speed for provided WWPN. - Send GIDPN asynchronously. The command will ask the switch to provide Nport ID for provided WWPN. - In driver unload path, schedule all session for deletion and wait for deletion to complete before allowing driver unload to proceed.
