This condition acts as the implicit end of the current buffer group. The last entry in the buffer list is handled as if the End RU flag were set. Thus, the last entry is handled as described above for the (0,1) or (1,1) values of (Begin RU, End RU). In all cases, when the end of the buffer list has been reached, all remaining data is formed into RUs and sent. Data is never carried forward to be used with the next SEND.
