1.  Introduction

   The recently proposed QUIC tunnel protocol
   [I-D.piraux-intarea-quic-tunnel] supports the exchange of IP packets
   and Ethernet frames over a QUIC connection.  Its two existing
   operating modes transports plain packets inside QUIC frames.  Their
   main advantage is that they support any network-layer protocol.
   However, this advantage comes with a large per-packet overhead since
   each packet contains both a network and a transport header.  All
   these headers must be transmitted in addition to the IP/UDP/QUIC
   headers of the QUIC connection.  For TCP connections for instance,
   the per-packet overhead can be large.

   In this document, we propose a new operating mode for the QUIC tunnel
   protocol, called the stream mode.  It takes advantage of the QUIC
   streams to efficiently transport TCP bytestreams over a QUIC
   connection.  Section 3 describes this new mode.  Section 5 specifies
   the format of the messages introduced by this document.  Section 6
