In my previous message I described three possible encapsulations of
Novell packets on Ethernet.  I missed one.  There is a fourth
encapsulation called the ISO compatible Novell (which seems much less
compatible with ISO than the third scheme I described but it's used
which the RFC1042 scheme is not).  This encapsulation puts a length in
the type field, has two bytes which look like the source and
destination SAPs of a SAP header (the bytes are both 0x11 in the
packet dumps I have) and then start off the XNS header with a checksum
of 0xFFFF (the flags and unnumbered data fields of the SAP header seem
to be missing).
