Section 4.12 says:
value : 0x89 = 137 binary: 10001001 decode: 10 -> Drop 001001 -> Fragmentation and DF set
It should say:
value : 0x89 = 137 binary: 10001001 decode: 10 -> Drop 001001 -> Bad TTL
Notes:
Per the "Reason Code (status = 10b, Dropped)" table, "Fragmentation and DF set" is code 000101b:
10 000101b = 133 = Fragmentation and DF set
whereas code 001001b is "Bad TTL":
10 001001b = 137 = bad TTL
