In this scenario I think it might be better to determine which
worker thread to hand the socket to based on the current RX queue
assignment.  This way you won't have to worry about what limit
the hardware has in terms of how many flows it can assign.

Of course if you can't modify the app then you'd have to rely on
hardware assignment.

Cheers,
