SO_REUSEPORT only works if you bind explicitly.
Henrik wants:
1) Automatically rotate through a set of source addresses
on each connect()
2) Allow automatic local port selection to use existing ports
when source addresses differ.
#2 is blocked by how tcp_{v4,v6}_get_port behave. #1 would be
a new feature to add to the routing code.
He doesn't want to have to explicitly bind to a particular saddr/
sport in order to get this but currently he has to.
