This case was not covered, and the wrong ID was set before the previous commit.
The rest is not modified, it is just that it will increase the code coverage.
The right address ID can be verified by looking at the packet traces. We could automate that using Netfilter with some cBPF code for example, but that's always a bit cryptic. Packetdrill seems better fitted for that.
