The test should already clean up after itself, by being run inside a
network namespace. That is a more robust method to ensure that all
state is reset.
The issue here is that the else branch is taken in
if [[ "$(ip netns identify)" == "root" ]]; then
./in_netns.sh $0 $@
else
main $@
fi
because the ip netns identify usually returns an empty string, not
"root". If we fix that, no need to add additional cleanup.
