scsi: mpt3sas: Add persistent MPI trigger page
This page is used to store information about MPI (IOC Status & LogInfo)
triggers.
Driver Persistent Trigger Page-4 format:
-------------------------------------------------------
| 31 24 23 16 15 8 7 0| Byte
-------------------------------------------------------
| PageType | PageNumber | Reserved | PageVersion | 0x00
--------------------------------------------------------
| Reserved | ExtPageType | ExtPageLength | 0x04
--------------------------------------------------------
| Reserved | NumMpiTriggerEntries | 0x08
--------------------------------------------------------
| MPITriggerEntry[0] | 0x0C
--------------------------------------------------------
| … |
--------------------------------------------------------
| MPITriggerEntry[19] | 0xA4
--------------------------------------------------------
NumMpiTriggerEntries:
This field indicates number of MPI (IOC Status & LogInfo) trigger entries
stored in this page. Currently driver is supporting a maximum of 20-MPI
trigger entries.
MPITriggerEntry:
-----------------------------------------------------
| 31 16 15 0 |
-----------------------------------------------------
| Reserved | IOCStatus |
-----------------------------------------------------
| IOCLogInfo |
-----------------------------------------------------
IOCStatus => Status value from the IOC
IOCLogInfo => Specific value that supplements the IOCStatus.
