We don't report it. What are you thinking you want to do with this
information?
I suppose it might be possible to teach libpcap/tcpdump about it, so
it can slide in an additional dissector. EDSA you can detect anyway,
since it uses a well know Ethertype. tcpdump already supports
this. But the other tag protocols cannot be detected.
devlink does seem like a good candidate for this, make it part of the
port type.
