I believe the convention is that normally the packet-list protocol and info
columns show information for the "highest-level" (innermost) protocol rather
than trying to show info about intermediate/encapsulating protocols.
(Note that a number of the packets in your capture file have 802.1Q
encapsulation ...).
So: I think the correct way would be at the beginning to do
col_set_str(...,COL_PROTOCOL, ...)
col_clear(...,COL_INFO)
and remove the col_... calls after the call_dissector(...).
Also: Since there are no preferences, the #include <prefs.h> is not needed.
Other than this the code looks good.
If you are OK with the above, you can just let me know and I'll commit the
dissector with the changes as above.
As a followup it would be much appreciated if you would add a page for the
TRILL protocol to the Wireshark Wiki (wiki.wireshark.org).

and http://wiki.wireshark.org/ProtocolReference
Thanks !!
