When a veth pair has one end in a container and the other in the host
namespace, removing it failed: the container end's teardown deleted the
whole pair, so the host end's own delete then failed ("Cannot find
device") and aborted the teardown, leaving the interface behind.
The host-namespace delete added for the both-ends-in-container case was
emitted for every container veth end. Restrict it to the primary end,
which for a host/container pair is the host end that already deletes the
pair itself.
Extend the container veth tests to remove the pair and verify it is gone,
covering both the single-end (regression) and both-ends teardown paths.
Fixes: #1546

==== Description
|
|
|
|
Verify connectivity with a simple web server container from behind a
|
|
regular bridge, a VETH pair connects the container to the bridge.

|
|
|
|
==== Sequence
|
|
|
|
. Set up topology and attach to target DUT
|
|
. Create 'web-br0-veth' container from bundled OCI image
|
|
. Verify container 'web-br0-veth' has started
|
|
. Verify basic DUT connectivity, host:data can ping DUT 10.0.0.2
|
|
. Verify container 'web-br0-veth' is reachable on http://10.0.0.2:91
|
|
. Remove container and VETH pair, verify clean teardown
