2017-02-09qla2xxx: Add framework for async fabric discoveryQuinn Tran1-7/+49
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.

2016-01-07qla2xxx: Enable Exchange offload support.Himanshu Madhani1-0/+5
This patch enables Exchange offload support in Qlogic ISP. To enable exchange offload with Qlogic ISP24XX/25XX/26XX, set module parameter ql2xexchoffld to any non-zero number. This will alow ISP firmware to store exchange data structures used by firmware to host memory provided by driver. ISP firmware can supports upto 32k total active exchanges.
