Prospects for per-receive queue tracing or perhaps tagging packets with their receive queue for later filtering?

[Rick Jones]

I find myself looking at the likes of ethtool -S output on a Linux
system, for a multi-queue NIC, and seeing drops reported for a specific
receive queue. I thus find myself wishing I could know which
packets/flows were arriving on that receive queue so I could,
presumably, figure-out who the "top talker" through that receive queue
might be.

I can find the top talker overall for traffic arriving on the NIC of
course, but that requires ass-u-me-ing that the top talker overall would
be the top talker on the queue with the drops, and given Murphy's Law
and differing IRQ assignments, that probably isn't a good assumption.

thoughts?
