Oh ow. Hopefully this is just for the RFC?

Yes, this is just for the RFC. Our focus was showing how PANDA
can easily replace flow dissector by using a useful and complex
use-case (flower) and extending it easily. A proper submission
would not linearize, but first we need feedback on how this
submission should look like.

Kind regards,
