This was covered in RFC 5880, §4.3/4.4:
Sequence Number
The sequence number for this packet. For Keyed MD5
Authentication, this value is incremented occasionally. For
Meticulous Keyed MD5 Authentication, this value is incremented for
each successive packet transmitted for a session. This provides
protection against replay attacks.
Similar text is present in -20 in section 5.
