Interesting to look back at this after the discussion of flow control. Take the MAX DATA frame. It does elicit an advertisement. It may be retransmitted, but really should not. Instead, if the packet carrying the frame is lost, the "receiver" (sender of MAX DATA) should check whether it already sent a MAX DATA frame carrying a higher limit, in which case there is no need for retransmission. If the frame is the newest, it should probably still not be retransmitted as is -- there may be a need to check create a new frame containing the latest MAX DATA value. So the MAX DATA frame elicits ACKS, its loss should be detected, but how retransmission proceeds depends on the state of the connection...
