Hi Brian,

Thanks for getting in touch. Is the flow sample pointed in your email an
example of one that does not get properly tagged? Besides, we should try
to make the issue reproducible: if you could make a pcap trace containing
some flow samples that should be tagged and they are not, and could share
it via unicast email, that would be fantastic.
