Section 8.3 says:


It should say:

      Assume that the sender receives two feedback packets with 
      Acknowledgement Numbers A1 and A2, respectively.  Further assume
      that the sender sent no data packets in between Sequence Numbers
      A1+1 and A2, inclusive.  (All those packets must have been pure
      acknowledgements, Sync and SyncAck packets, and so forth.)  Then
      the sender MAY, at its discretion, ignore the second feedback
      packet's Receive Rate option.  Note that when the sender decides
      to ignore such an option, it MUST NOT reset the nofeedback timer
      as it normally would; the nofeedback timer will expire as if the
      second feedback packet had not been received.


This is a new paragraph to be added to the end of Section 8.3.
It specifies that if the interval covered by a feedback packet doesn't include
any data packets, then the sender doesn't have to use the reported receive rate.
