        With the rr_tx_counter is per-cpu, each CPU is essentially doing
its own round-robin logic, independently of other CPUs, so the resulting

multiple CPUs could select the same interface to transmit on
approximately in lock-step).  I'm not sure if this could cause actual
problems in practice, though, as particular flows shouldn't skip between
CPUs (and thus rr_tx_counters) very often, and round-robin already
shouldn't be the first choice if no packet reordering is a hard
requirement.

        I think this patch could be submitted against net-next
independently of the rest of the series.

Yes this makes sense. I'll submit it separately against net-next today
and drop it off from this patchset.
