I've checked in an implementation of that, along with:
a "wka.tmpl" file containing a bunch of well-known MAC addresses
and address ranges;
an updated to "make-manuf" to append that file to the end of
"manuf";
an updated "manuf" file (which, being the result of
"make-manuf", includes some updates to the OUIs).
Currently, the bytes not completely covered by the netmask have those
bits not covered by the netmask appended to the string from the file,
with a "_" as a separator.
However, currently, names for MAC addresses, MAC address ranges, and
vendors can contain no spaces - the first space and everything after it
is ignored.
It might be nice, for OUIs, to be able to display the full vendor name,
although I'm not sure how that would best be done - something such as
Source: 00:e0:52:66:66:66 (FOUNDRY_66:66:66 - FOUNDRY NETWORKS, INC.)
might do it, but that does run the risk of making the line too long.
Furthermore, for the well-known addresses, just chopping off the first
token from the description wouldn't be enough; for example, two of the
well-known addresses I added to "wka.tmpl" from the cavebear.com list
are
01-00-10-00-00-20 Hughes Lan Systems Terminal Server S/W download
01-00-10-FF-FF-20 Hughes Lan Systems Terminal Server S/W request
but I had to replace the spaces in the description with hyphens
(underscores would also have worked; I guess, on some platforms with
some fonts, ISO 8859/x non-breaking space would have worked as well, but
that wouldn't necessarily work everywhere you'd want it to) so that
those addresses didn't just show up as "Hughes".
It might be nice to allow those to display as "Hughes Lan Systems
Terminal Server S/W download" and "Hughes Lan Systems Terminal Server
S/W request".
Furthermore, it might be nice to have well-known address ranges have a
printf-style format string as the name, e.g.
00-00-5E-00-01/40 IETF VRRP virtual router VRID=%u
(or %x, if people prefer the VRID to display in hex). Whether we should
have a format item for each byte not completely covered by the netmask,
or combine those bytes into an up-to-64-bit number and just print that
number, is another matter; the latter is trickier, as not all compilers
with which Ethereal is built support 64-bit integral data types *AND*
the formats used for those data types aren't standardized, so to make
that work we'd have to parse the format string ourselves rather than
having the OS's printf routines do it.
