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.

- Put the current accumulated total in each IOCB in the chain as we are

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

- 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)

with 0x80000000.
