[P4-dev] Any use case for resubmit and recirculation in P4?

Dear all,

I noticed that P4 provides primitive operations like resubmit and recirculation. They can redirect packet back to the Parser to have different parsing decisions.

I'm wondering what kind of scenario when we need "different parsing decisions"? Any hint is appreciated.

Best Regards,
