Draft 07 of DDP in clause 7.1 states: If the DDP layer detects any of the receive errors listed in this section, it MUST cease placing the remainder of the DDP Segment and report the error(s) to the ULP. The DDP layer SHOULD include in the error report the DDP Header, the type of error, and the length of the DDP segment, if available. Draft 07 or RDMAP in figure 10 for a DDP error places a "YES" in the column that identifies the DDP header as being required. The question is "Does she or doesn't she".. Have to provide the DDP header?
