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