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.

The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway. We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

Miscellanous logic and interface fixes
- Fix lpfc_init_vfi_cmpl to check the interface type for interface type 0
before parsing the results.
- Cast uint32_t values that are multiplied to uint64_t before the
multiplication.
- Instead of "break" statement when PCI read returned error, use the goto
statement to the end of the routine after setting return value
- moved the msleep(10) to the beginning of the wait loop for checking the
SLIPort_Status register
- Added the code to follow the existing wait for SLIPort_Status register RDY,
ERR, and RN bits to be set by the port before proceeding to perform PCI
function reset.
- Do not override ulpCt_h and ulpCt_l for SLI 4 ports.
- For vport delete, call lpfc_nlp_put when the vport's vpi state is not
marked with VPI_REGISTERED.
- Added missed fields into the driver's Controller Attributes Structure
- Changed ringing EQ/CQ/RQ doorbell register to be dependent on the size
of the queue.
- Return -EACCES in issue_reset if cfg_enable_hba_reset is zero.
- Added new logging flag LOG_FCP_UNDER 0x00040000 to qualify underrun logging.
- Add a check in the fabric name display routine to display 0 if the port
state is <= FLOGI.
- Add a check to the switch statement in lpfc_decode_firmware_rev to check
for an 'X'.

Fix SYSFS interface issues.
- In the lpfc_sli4_pdev_status_reg_wait() routine, after initial 100ms delay
following write to PHYSDEV_CONTROL register for the firmware reaction, check
the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them
became 1, the previous PHYSDEV_CONTROL register should be considered failed
due to lack of privilege and error for no permission should be returned
immediately without getting into the wait for RDY bits on the SLIPORT_STATUS
register.
- Remove the driver check on dev->is_physfn before proceed to perform the
PHYSDEV_CONTROL register write, and let the PCI function's privilege
setting and driver handling of PHYSDEV_CONTROL register write failure to
handle the reset-ability through the SLI port.
- Added key to ctlreg_write to prevent unauthorized or unexpected write to
the control register.
- Change return to EACCES for sysfs access that are failed because hba_reset
is disabled.

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.

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.

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.
- Replace many calls to the initial_flogi routine with lpfc_issue_init_vfi.
- Add vp and vpi fields to the INIT_VFI mailbox command.
- Addapt lpfc_hba_init_link routine for SLI4 use.
- Use lpfc_hba_init_link call from lpfc_sli4_hba_setup.
- Add a check for FC mode to register the FCFI before init link.
