No reconnections necessary.

I believe you misunderstood : On the 4-tuple (SADDR,SPORT,DADDR,DPORT),
you can pick for example SPORT so that hash(SADDR,SPORT,DADDR,DPORT)
maps to a known and wanted RX queue number.

Once you know that, you use bind(SADDR, SPORT), then
connect(DADDR,DPORT). 

Anyway, if your hardware is able to cope with the few number of flows,
just use the hardware and be happy.

Here we want about 10 millions sockets, there is little hope for
hardware being helpful.
