James Smart 5350d872c1 [SCSI] lpfc 8.3.27: Fix queue allocation failure recovery
Fix queue allocation failure recovery

- Move the allocation of the Queues closer to the creation of the queues.
- If there is a problem with creation, or if the HBA is reset, the queues
  will be completely freed and re allocated.
- Only allocate fcp_eq_hdl if cfg_fcp_eq_count is non-zero.

James Smart 7d791df730 [SCSI] lpfc 8.3.25: Add FCF priority failover functionality
This patch implements a new FCF failover policy for the lpfc driver. It
allows the driver to choose which FCF to failover to based on the FCF
priority. This patch also introduces a new sysfs parameter
(fcf_failover_policy) to allow the user to choose which FCF failover policy
to use.

- Added capturing dumping capabiliy of mailbox command and external buffer
  for the completion of the mailbox command so that the outcome can be
  examined.
- Changed all the iDiag command structure data array indexing introduced so
  far with properly defined macros.
- Added SLI4 device PCI BAR memory mapped register read/browse, write-by-
  value, set-bit, and clear-bit methods for both interface type 0 and

James Smart 0a96e9754d [SCSI] lpfc 8.3.25: PCI and SR-IOV Fixes
PCI and SR-IOV Fixes

- Call pci_save_state after the pci_restore_state completes.
- After calling pci_enable_pcie_error_reporting() and checking the return
  value for logging messages from rc, reset rc to 0 to it will not later be
  interpreted for error.
- Read PCI config space SR-IOV capability to get the number of VFs supported.
- Check for the PF's supported number of VFs before invoking PCI enable sriov
  API call and log error message that user requested number of VFs is beyond
  the PF capability if such request is passed in.
- Added check for Physical function with Virtual Functions attached. If so,
  first disable all the VFs before proceeding to device reset.

James Smart 7851fe2c7f [SCSI] lpfc 8.3.25: Adapter Interface fixes and changes
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.

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

  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.

Add SLI4 FC Discovery support

- 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.

  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.

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 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
