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.

Miscellanous logic and interface fixes
- Fix lpfc_init_vfi_cmpl to check the interface type for interface type 0
before parsing the results.

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.

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.
