Right; note that that measures time to establish a new connection, not
the delay of packets within an already established connection. My guess
would be that each established connection would have a new source port,
thus hashing into a new bin.

I'm pretty sure it supports the normal classifier (tc filter). That
overrides the built-in hashing completely, but IIRC you can do your own
hashing in tc filter :)
