Can you please explain why you believe the original license of TIPC is GPL-2.0 and not dual-licensed?
Do you have evidence outside of the kernel repository and commit history that you are referring to?

The current text in the headers of all these files contains the full, exact text of the BSD-3-Clause
license, along with a statement that "Alternatively, this software may be distributed under the terms of the
GNU General Public License ("GPL") version 2 as published by the Free Software Foundation."  This has
been the case since 2006, when this code was introduced into the kernel source tree*.

This is the one of the most unambiguous cases of dual licensing I have encountered while working on
these SPDX ID Lines.
 -- Tim

* Details:
Per Lindon, working for Ericsson, introduced most of these files on Jan 2, 2006, with a BSD-3-Clause
license.  Most of the files were introduced with commit b97bf3fd8f6a
On Jan 11, 2006, a little over a week later, Per clarified that the license was intended to be dual licensed,
and added the "Alternatively..." clause.  This was in commit 9ea1fd3c1a15.
