I think we already discussed of the current issues of current code.
Telling people to spread SYN to several cpus is a good way to have a
freeze in case of synflood, because 15 cpus are busy looping while one
is doing progress.
Thats why Intel felt the need of a hardware filter to direct all SYN
packets on a single queue.
