Definitely happy to put it in a generic place like netdev_rx_queue.c
like you did, but slight pushback to putting it into its own series.
With the ndos merged finally, I can take our devmem TCP series out of
RFC and I am eager to do so. Making it dependent on a change that is
in another series means it must remain RFC.

What I can do here is put this change into its own patch in the devmem
TCP series. Once that is reviewed the maintainers may apply that patch
out of the series. I can also put it in its own series and keep devmem
TCP in RFC for now if you insist :D
