tcpEStatsStackSoftErrorReason

This object identifies which consistency test most recently
failed during TCP input processing.  This object SHOULD be
set every time tcpEStatsStackSoftErrors is incremented.  The
codes are as follows:
              
belowDataWindow(1) - All data in the segment is below
SND.UNA. (Normal for keep-alives and zero window probes).
              
aboveDataWindow(2) - Some data in the segment is above
SND.WND. (Indicates an implementation bug or possible
attack).
              
belowAckWindow(3) - ACK below SND.UNA. (Indicates that the
return path is reordering ACKs)
              
aboveAckWindow(4) - An ACK for data that we have not sent.
(Indicates an implementation bug or possible attack).
              
belowTSWindow(5) - TSecr on the segment is older than the
current TS.Recent (Normal for the rare case where PAWS
detects data reordered by the network).
              
aboveTSWindow(6) - TSecr on the segment is newer than the
current TS.Recent. (Indicates an implementation bug or
possible attack).
              
dataCheckSum(7) - Incorrect checksum.  Note that this value
is intrinsically fragile, because the header fields used to
identify the connection may have been corrupted.
              
otherSoftError(8) - All other soft errors not listed
above.
