    _______________________________________________________

Details:

if a pbuf received with the same seqno in ooseq ,
we then check  the size and replace the existing one
with the larger one,but if the existing one is the
last segment in ooseq ,it might has been trimed before.
the replacing action will overrun our receive windows
