Hmm, for me the main point was to keep the complete processing
of a single packet within one CPU/Core where this is a non-issue.
But the interrupt for a packet can be received by cpu 0 whereas the rest of processing proceeds on cpu 1; so it still helps to keep the producer index and consumer index on separate cachelines.
