MFC r331926:
  r330675 introduced an extra window check in the LRO code to ensure it
  captured and reported the highest window advertisement with the same
  SEQ/ACK.  However, the window comparison uses modulo 2**16 math, rather
  than directly comparing the absolute values.  Because windows use
  absolute values and not modulo 2**16 math (i.e. they don't wrap), we
  need to compare the absolute values.
