Joachim Wiberg 1bbd80d8c7 test: drop leading ietf/infix prefix from directories
Let's drop the leading IETF or Infix prefixes from tests.  Initially the
idea was to mimnic the YANG models, but it's difficult to navigate and
does not provide any real benefit to developers or end-users.

=== VLAN Interface Termination

ifdef::topdoc[:imagesdir: {topdoc}../../test/case/interfaces/vlan_iface_termination]

==== Description

Verify that VLANs stacked on top of an interfaces that are also
attached to a VLAN filtering bridge are always locally terminated.

In this setup, even though VLAN 10 is allowed to ingress and egress on
both `data1` and `data2`, _bridging_ of packets from one to the other
must _not_ be allowed.

==== Topology

image::topology.svg[VLAN Interface Termination topology, align=center, scaledwidth=75%]

==== Sequence

. Set up topology and attach to target
. Configure bridge and VLAN interfaces on target
. Configure IP addresses and VLAN interfaces on host
. Verify that host:data1 reaches host:data2 with untagged packets
. Verify that traffic on VLAN 10 from host:data1 does not reach host:data2
. Verify that host:data1 can reach target on VLAN 10
. Verify that host:data2 can reach target on VLAN 10
