Section Appendix B says:

  o  <msg-hop-limit> field, if present, contains the number of hops on
     which the packet is allowed to travel before being discarded by a
     MANET router.  The <msg-hop-limit> is set by the message
     originator and is used to prevent messages from endlessly
     circulating in a MANET.  When forwarding a message, a MANET router
     should decrease the <msg-hop-limit> by 1, and the message should
     be discarded when <msg-hop-limit> reaches 0.

  o  <msg-hop-count> field, if present, contains the number of hops on
     which the packet has traveled across the MANET.  The <msg-hop-
     count> is set to 0 by the message originator and is used to
     prevent messages from endlessly circulating in a MANET.  When
     forwarding a message, a MANET router should increase <msg-hop-
     count> by 1 and should discard the message when <msg-hop-count>
     reaches 255.

It should say:

  o  <msg-hop-limit> field, if present, contains the number of hops on
     which the message is allowed to travel before being discarded by a
     MANET router.  The <msg-hop-limit> is set by the message
     originator and is used to prevent messages from endlessly
     circulating in a MANET.  When forwarding a message, a MANET router
     should decrease the <msg-hop-limit> by 1, and the message should
     be discarded when <msg-hop-limit> reaches 0.

  o  <msg-hop-count> field, if present, contains the number of hops on
     which the message has traveled across the MANET.  The <msg-hop-
     count> is set to 0 by the message originator and is used to
     prevent messages from endlessly circulating in a MANET.  When
     forwarding a message, a MANET router should increase <msg-hop-
     count> by 1 and should discard the message when <msg-hop-count>
     reaches 255.

Notes:

Two changes of "packet" to "message". Message is consistent with the normative Section 5.2 that defines these fields (which may appear in each message, so are not uniquely defined for a packet), the text introducing these bullet points, and the remainder of these paragraphs.

(Note that the original and corrected text has had indentation reduced by one space.)
