James Smart c71ab8616d [SCSI] lpfc 8.3.36: Fixed boot from san failure
Fixed boot from san failure when SLI4 FC device presented on the same PCI bus

The request_firmware interface can induce delays while looking
for firmware files, even if no fw file is present. In some situations
the delays exceeded scan_wait timeouts, resulting in situations in which
the boot device had not been discovered in time.  Boot Device does not
need to be on a lpfc device.

Change request_firmware use to be module paramater driven. Default is to
not attempt firmware download on boot. Add sysfs parameter to invoke
firmware update.

Adapter Interface fixes and changes

- Modify the macro field from lpfc_init_vpi_vpi to lpfc_init_vfi_vpi
- Add the new CQE_CODE_RECEIVE_V1 CQE Code, add code in the driver to handle
  the new Code the same as the CQE_CODE_RECEIVE code except that there are
  two new checks for this code that will cause the driver to use the new V1
  macros for rq_id and fcf_id.
- Fix a bug in lpfc_prep_seq() where the size out of the first CQE was
  ONLY being used, even though multiple dmabufs make up the sequence,
  each have their own CQE with potentially different sizes.
- Fix bug in lpfc_bsg_ct_unsol_event() where the ulpContext and ulpWord[3]
  fields of the XMIT_SEQUENCE64_CX IOCB were being calculated incorrectly.
- Do physical to logical translation before indexing into the active
  XRI array.
- Populate physical vpi in the iocb data structure.
- Put the current accumulated total in each IOCB in the chain as we are
  walking thru then. The last IOCB in the chain should have the total
  length of the sequence.

James Smart 0558056c1e [SCSI] lpfc 8.3.24: Miscellaneous Fixes and Corrections
Miscellaneous Fixes and Corrections
- Remove the memset in the lpfc_sli4_remove_rpi_hdrs call.
- Correct swapping of SGE word 2 relative to offset value
- Reorganize CQ and EQ usage to comply with SLI4 Specification.
- Expand the driver to check the rn bit. Only detect an error if the error bit
  is set and the RN bit is NOT set.
- If mailbox completion code is not success AND the mailbox status is success,
  then and only then will the driver overwrite the mailbox status.
- When driver initializing device, if the device is on a PCIe bus, set
  PCI's "needs fundamental reset" bit so that EEH uses fundamental reset
  instead of hot reset for recovery.
- Prevent driver from using new WWN when changed in firmware (until driver
  reload)
- When HBA reports maximum SGE size > 0xffffffff (infinite), override
  with 0x80000000.
- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
  unregistering the fcf if Devloss fires before Delay discover timer fires.

- Replace READ_LA and READ_LA64 with READ_TOPOLOGY mailbox command.
- Converted the old READ_LA structure to use bf_set/get instead of bit fields.
- Rename HBA_FCOE_SUPPORT flag to HBA_FCOE_MODE. Flag now indicates function
  is running as SLI-4 FC or FCoE port. Make sure flag reset each time
  READ_REV completed as it can dynamically change.
- Removed BDE union in the READ_TOPOLOGY mailbox command and added a define to
  define the ALPA MAP SIZE. Added FC Code for async events.
- Added code to support new 16G link speed.
- Define new set of values to keep track of valid user settable link speeds.
- Used new link speed definitions to define link speed max and bitmap.
- Redefined FDMI Port sppeds to be hax values and added the 16G value.
- Added new CQE trailer code for FC Events.
- Add lpfc_issue_init_vfi and lpfc_init_vfi_cmpl routines.

James Smart a93ff37a8a [SCSI] lpfc 8.3.18: Add logic to detect last devloss timeout
Added driver logic to detect the last devloss timeout of remote nodes which
was still in use of FCF. At that point, the driver should set the last
in-use remote node devloss timeout flag if it was not already set and should
perform proper action on the in-use FCF and recover of FCF from firmware,
depending on the state the driver's FIP engine is in.

Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful
recovery from devloss timeout.

James Smart da0436e915 [SCSI] lpfc 8.3.2 : Addition of SLI4 Interface - Base Support
Adds new hardware and interface definitions.

Adds new interface routines - utilizing the reorganized layout of the
driver. Adds SLI-4 specific functions for attachment, initialization,
teardown, etc.

James Smart 3772a99175 [SCSI] lpfc 8.3.2 : Reorganization for SLI4
Preps the organization of the driver so that the bottom half, which
interacts with the hardware, can share common code sequences for
attachment, detachment, initialization, teardown, etc with new hardware.

For very common code sections, which become specific to the interface
type, the driver uses an indirect function call. The function is set at
initialization. For less common sections, such as initialization, the
driver looks at the interface type and calls the routines relative to
the interface.

James Smart a257bf905e [SCSI] lpfc 8.3.1: misc fixes/changes
8.3.1 Fixes/Changes :

- Fix incorrect byte-swapping on word 4 of IOCB (data length) which
  caused LUNs to not be discovered on big-endian (e.g. PPC)

- Remove a bad cast of MBslimaddr which loses the __iomem (sparse)

- Make lpfc_debugfs_mask_disc_trc static (sparse)

- Correct misspelled word BlockGuard in lpfc_logmsg.h comment

- Replaced repeated code segment for canceling IOCBs from a list with
  a function call, lpfc_sli_cancel_iocbs().

- Increased HBQ buffers to support 40KB SSC sequences.

- Added sysfs interface to update speed and topology parameter without
  link bounce.

- Fixed bug with sysfs fc_host WWNs not being updated after changing
  the WWNs.

- Check if the active mailbox is NULL in the beginning of the mailbox
  timeout handler - fixes panic in the mailbox timeout handler while
  running IO stress test

- Fixed system panic in lpfc_pci_remove_one() due to ndlp indirect
  reference to phba through vport

- Removed de-reference of scsi device after call to scsi_done() to fix
  panic in scsi completion path while accessing scsi device after
  scsi_done is called.

- Fixed "Nodelist not empty" message when unloading the driver after
  target reboot test

- Added LP2105 HBA model description

- Added code to print all 16 words of unrecognized ASYNC events

- Fixed memory leak in vport create + delete loop

- Added support for handling dual error bit from HBA

- Fixed a driver NULL pointer dereference in lpfc_sli_process_sol_iocb

- Fixed a discovery bug with FC switch reboot in lpfc_setup_disc_node

- Take NULL termintator into account when calculating available buffer space

James Smart 5b75da2fa2 [SCSI] lpfc 8.3.0 : Add active interrupt test for enabling MSI/MSI-X/INTx
Per the recent discussions at the Linux Plumbers Conference, when
enabling MSI or MSI-X, generate a test interrupt to verify the
interrupt routing is working properly.  If the test interrupt fails,
fall back to MSI first, and if that fails as well, to INTx.  If the
interrupt test fails with INTx, log an error and fail the PCI probe.

Also changed the use of spin_(lock|unlock) to the _irq(save|restore)
variants in the interrupt handlers because with multi-message MSI-X,
both interrupt handlers can now run in parallel.

James Smart eada272dfc [SCSI] lpfc 8.3.0 : Fix multiple NPIV issues
- Fix lock up on rmmod with vports defined by having
  lpfc_pci_remove_one() invoke fc_vport_terminate() to remove all the
  vports before invoking fc_remove_host() for the physical port

- Fix echotest failure when NPIV is enabled

- Add the vport_disable function to the physical port's transport
  template to make the vport disable attribute visible

- Set the vport state to DISABLE on create if the disable flag is
  true

- Call lpfc_alloc_sysfs_attr() for vports so that statistical data
  collection works on them

- Support setting a vport's symbolic name via sysfs by writing to
  /sys/class/fc_vport/vportX/symbolic_name

- Fix create vport fails when link is down or in loop mode.  Should be
  able to be create vports any time NPIV is enabled

- Fix slow vport deletes when deleting multiple vports at once

lpfc_max_scsicmpl_time. The attributes control statistical reporting
of io load.

Added support for new fc vendor events for error reporting.
