Hello!
Thank you!
I can replicate error:

It's slightly tricky to investigate this case as it's nested deeply in sFlow packet.
Can you capture pcap of GRE with IPv6 inside? Few packets should be enough.
Thank you!
Here's the PCAP data with some GRE IPv6.
IPv6 is not unpacked correctly with the unpack_gre flag with the sflow_plugin.
