Short answer: yes. If you imagine several frames on the pending frame queue - all of which end up enqueueing buffer indices to a common successor node - the successor frame will be merged by the time it’s processed.
We’ve seen this effect when handing off frames from multiple source threads to a common destination: 10 buffer indices from thread A + 10 buffer indices from thread B => 20 buffer indices by the time they’re processed by thread C. Within reason, it’s a feature. Nodes are more efficient when processing large vectors...

Hi, The packets in a frame (a batch of packets) can be split (if they goes to different next node). Are there places where packets from different frames are merged into one frame?
