Is skb->queue_mapping valid for received packets?

Anyone know if skb->queue_mapping is set for incoming packets, ie to
notify which queue they came in on?  I can't find it set anywhere,
and it appears it is sometimes set to 1 when it should be 0 in
my system.

Maybe it's never actually set, and I'm just reading some stale
data?

Thanks,
Ben
