# 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.
