This is bitmap of received and failed frames in the aggregation. Rate scale algorithm should not be concern with parsing BACK frame so the info is summarized to something useful to rate scale algorithm at least to what we believe is. We don't have much information as other vendor view this. The bitmap is useful to keep statistic window accurate. All the frames are sent in same rate (currently we didn't see other implementation) > Broadcom hardware is able to give intermediate status notifications, > would there be any use in those?
