STREAMS message types differ in their intended purposes, their treatment at the stream head, and their message-queueing priority.
STREAMS does not prevent a module or driver from generating any message type and sending it in any direction on the stream. However, established processing and direction rules should be observed. Stream head processing according to message type is fixed, although certain parameters can be altered.
