In DSACK case, some events are not extraordinary, such as packet duplication generated DSACK. They can arrive easily below snd_una when undo_marker is not set (TCP being in CA_Open), counting such DSACKs amoung SACK discards will likely just mislead if they occur in some scenario when there are other problems as well. Similarly, excessively delayed packets could cause "normal" DSACKs. Therefore, separate counters are allocated for DSACK events.
