Hmm.

You could also add to "/etc/ethers" on UNIX systems, or to the "ethers"
file in the Ethereal installation directory on Windows, entries for the
MAC addresses in question; that wouldn't require any code changes.

If it's inconvenient or undesirable to add them to "/etc/ethers" on
UNIX, we could modify "initialize_ethers()" in "epan/resolv.c" to read a
file in both the "get_datafile_dir()" and the "get_systemfile_dir()"
directory, if those two routines don't return the same path (on Windows,
they do).

We could then ship an "ethers" file with Ethereal that contains
well-known MAC addresses - and that could be updated with no code
changes.
