You should take this opportunity to document the logic
for the allocation and peering of hairpin queues.

It would be good to add short code comments for the variables as well.
It confusing to have hairpinq and hairpin_q variables.

Currently, we cannot really understand whether this fix is good or not.

On hairpin topic, I suggest fixing this typo:
	hairping-rss -> hairpin-rss
