[SCSI] lpfc: Fix error loading on sparc
Bug reported via SourceForge - lpfc does not load on sparc. The lpfc driver must byteswap all FCP IOCBs to recover the data into cpu native format. Also correct issue of "iotag not found" messages Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
