Notes:
======

Design for a general purpose DL mux:
------------------------------------

When DL streams are opened, attach them to network devices and marshall
packets between the DL streams and the Linux packet layer.

When CD streams are linked under the mux, make network devices out of
them and marshall packets between the network device and the CD stream.

Design for a general purpose NP mux:
------------------------------------

When N streams are opened, bind them to network protocols and marshall
packets between then N stream and the Linux packet layer.  In general,
there is a different N stream for each DL mac type.  Protocol ids are
interpreted in accordance with the mac type.  So, for example, for
DL_ETHER, the protocol id is an EtherType.  For DL_IP, the protocol id
is an IP protocol number.

When DL streams are linked under the mux, make network devices out of
them and marshall packets between the network device and the DL stream.
