------- Comment #2 from sebastien@xxxxxxxxx  2007-03-27 01:02 GMT -------
The ethertype is *not* the only "magic number" existing at layer 2. For
example, there is frame relay which is not using ethertype, or in ipv6 over ppp
(others?). There is even a trace on the wireshark captures museum which is raw
IPv6 packets ... no ethertype, in fact there is no type at all at layer 2. For
all these reasons, it makes much more sense to use ip.version == 6 than using
the ethertype.
And even if it was the same "magic number" for every underlying layer, I don't
see any reason why people could not expect to build a display filter on an
existent field.

I recently made modifications to IPv6 to update it. The patch has not yet been
reviewed. I will send it again with modifications inspired by the comments of
Ulf.
