This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2017-03-18qla2xxx: Fix delayed response to command for loop mode/direct connect.Quinn Tran
Current driver wait for FW to be in the ready state before processing in-coming commands. For Arbitrated Loop or Point-to- Point (not switch), FW Ready state can take a while. FW will transition to ready state after all Nports have been logged in. In the mean time, certain initiators have completed the login and starts IO. Driver needs to start processing all queues if FW is already started.

2017-03-18qla2xxx: Change scsi host lookup method.Quinn Tran
For target mode, when new scsi command arrive, driver first performs a look up of the SCSI Host. The current look up method is based on the ALPA portion of the NPort ID. For Cisco switch, the ALPA can not be used as the index. Instead, the new search method is based on the full value of the Nport_ID via btree lib.

The Mailbox interface is currently over subscribed. We like to reserve the Mailbox interface for the chip managment and link initialization. Any non essential Mailbox command will be routed through the IOCB interface. The IOCB interface is able to absorb more commands. Following commands are being routed through IOCB interface - Get ID List (007Ch) - Get Port DB (0064h) - Get Link Priv Stats (006Dh) Signed-off-by: Quinn Tran <quinn.tran@cavium.com> Signed-off-by: Himanshu Madhani <himanshu.madhani@cavium.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
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.
