|
|
* HostIndex and IocIndex. Added Alias.
|
|
* 01-09-01 01.01.02 Added defines for TARGET_ASSIST_FLAGS_REPOST_CMD_BUFFER
|
|
* and TARGET_STATUS_SEND_FLAGS_REPOST_CMD_BUFFER.
|
|
* 02-20-01 01.01.03 Started using MPI_POINTER.
|
|
* Added structures for MPI_TARGET_SCSI_SPI_CMD_BUFFER and
|
|
* MPI_TARGET_FCP_CMD_BUFFER.
|
|
* 03-27-01 01.01.04 Added structure offset comments.
|
|
* 08-08-01 01.02.01 Original release for v1.2 work.
|
|
* 09-28-01 01.02.02 Added structure for MPI_TARGET_SCSI_SPI_STATUS_IU.
|
|
* Added PriorityReason field to some replies and
|
|
* defined more PriorityReason codes.
|
|
* Added some defines for to support previous version
|
|
* of MPI.
|
|
* 10-04-01 01.02.03 Added PriorityReason to MSG_TARGET_ERROR_REPLY.
|
|
* 11-01-01 01.02.04 Added define for TARGET_STATUS_SEND_FLAGS_HIGH_PRIORITY.
|
|
* 03-14-02 01.02.05 Modified MPI_TARGET_FCP_RSP_BUFFER to get the proper
|
|
* byte ordering.
|
|
* 05-31-02 01.02.06 Modified TARGET_MODE_REPLY_ALIAS_MASK to only include
|
|
* one bit.
|
|
* Added AliasIndex field to MPI_TARGET_FCP_CMD_BUFFER.
|
|
* 09-16-02 01.02.07 Added flags for confirmed completion.
|
|
* Added PRIORITY_REASON_TARGET_BUSY.
|
|
* 11-15-02 01.02.08 Added AliasID field to MPI_TARGET_SCSI_SPI_CMD_BUFFER.
|
|
* 04-01-03 01.02.09 Added OptionalOxid field to MPI_TARGET_FCP_CMD_BUFFER.
