4 # This test sends traffic from H1 to H2. Either on ingress of $swp1, or on
5 # egress of $swp2, the traffic is acted upon by an action skbedit priority. The
6 # new priority should be taken into account when classifying traffic on the PRIO
7 # qdisc at $swp2. The test verifies that for different priority values, the
8 # traffic ends up in expected PRIO band.
