From: William Tu <u9012...@gmail.com> This test highlights a bug that was affecting master up until the previous patch. Put simply, we have two bridges: an integration bridge which contains a tunnel, and a physical bridge for underlay network connectivity. This test simulates putting UDP traffic through the integration bridge, with the intention to apply GRE tunnel headers and send the packet through the underlay bridge. The underlay bridge should observe GRE traffic. --- tests/tunnel-push-pop.at | 69 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+)
