The problem with you algorithm is that you cannot control
how to NIC puts incoming packets into RX rings (and then 
actually if the packets you are interested in do actually arrive from
the net ,-)

While some NICs have hardware support to get high priority
packets into different queues these tend to add nasty limits
on the max number of connections. Which IMHO is not acceptable.

support four swap devices"
