That looks like an "advertising clause", which, I think, renders the
license in the copyright notice incompatible with the GPL (the license
under which Ethereal is released):
http://www.gnu.org/licenses/license-list.html#GPLIncompatibleLicenses
"GPL-Incompatible, Free Software Licenses
The following licenses are free software licenses, but are not
compatible with the GNU GPL:
...
The original BSD license.
(Note: on the preceding link, the original BSD license is listed in the
"UCB/LBL" section.) This is a simple, permissive non-copyleft free
software license with a serious flaw: the ``obnoxious BSD advertising
clause''. The flaw is not fatal; that is, it does not render the
software non-free. But it does cause practical problems, including
incompatibility with the GNU GPL.
We urge you not to use the original BSD license for software you write.
If you want to use a simple, permissive non-copyleft free software
license, it is much better to use the modified BSD license or the X11
license. However, there is no reason not to use programs that have
been released under the original BSD license."
