Sorry to chime in a bit late, but this recirculation performance penalty for

it to the destination (e.g. a local VM), does not look appealing at all.
To allow having the best of both worlds (avoid perf penalty in all cases,
but avoid complex code to automatically determine whether recirculation is
needed or not), would it be possible to specify in a flow, after an mpls
match, whether or not recirculation is wanted ?
No. That would be a layering violation.
I don't get what kind of layering violation you see.
Can you explain?
If you can find a better way to do it, that is maintainable, we'd be
open to that.
What about:
- adding a parameter to the pop_action (recirculate after pop, or don't
recirculate after pop)
- or keep the current pop, and add a pop_and_do_not_recirculate
- or add an explicit recirculate action, and by default do not recirculate
?
