This commit greatly simplifies AsciiDoc image references in generated Readme.adoc files. The two focused use-cases that remain after this change are working references in: - Generated output/images/test-report.pdf - Viewing test's Readme.adoc from GitHub Previously we aimed to have working images also when the test's Readme was included in the parent directory's Readme.adoc. This, however, is not supported as of this commit. It seems unlikely also to ever be a supported feature of AsciiDoc on GitHub, for details, see the following issue: <https://github.com/github/markup/issues/1095> Signed-off-by: Joachim Wiberg <troglobit@gmail.com>

==== Description

the flooding stops as soon a join arrives

==== Sequence
. Set up topology and attach to target DUTs
. Configure device
. Start multicast sender on host:data0, group 224.1.1.1
. Verify that the group 224.1.1.1 is flooded on host:data2 and host:data3
. Join multicast group 224.1.1.1 on host:data2
. Verify group 224.1.1.1 is received on host:data2
. Verify that the group 224.1.1.1 is no longer received on host:data3
