2017-08-24scsi: qla2xxx: Add ability to autodetect SFP typeQuinn Tran
SFP can come in 2 formats: short range/SR and long range/LR. For LR, user the can increase the number of Buffer to Buffer credits between end points via Cavium's command line tool. By default, FW uses a lower BB Credit value optimized for SR. This patch will read the SFP for each link up event and during chip reset sequence. If the SFP type and setting are mismatch, then the chip is reset 1 time to use the appropriate setting.

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.

Previously, the ql2xexchoffld module parameter was used to control the max number of exchanges to be offload onto host memory. Module parameter ql_dm_tgt_ex_pct was used to control the percentage of exchanges allocated to the Target side. With this patch, module parameter ql_dm_tgt_ex_pct is no longer used to control exchanges for the driver. New module parameter ql2xiniexchg is added to control exchanges between target mode and initiator mode. With the updated module parameters, users can control the exact number of exchanges for either Initiator or Target. The exchange offload feature will be automatically enabled when the total number of exchanges exceeds 2048 limit.

2017-02-09qla2xxx: Improve RSCN handling in driverQuinn Tran
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 Tran
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.
