    sys/kern             uipc_socket.c 
  Log:
  When doing a recv(.. MSG_WAITALL) for a message which is larger than
  the socket buffer size, the receive is done in sections.  After completing
  a read, call pru_rcvd on the underlying protocol before blocking again.
  
  This allows the the protocol to take appropriate action, such as
  sending a TCP window update to the peer, if the window happened to
  close because the socket buffer was filled.  If the protocol is not
  notified, a TCP transfer may stall until the remote end sends a window
  probe.
