Short-lived connections increase the insertion rate requirements,
fill the offload table and provide very limited offload value since
they process a very small amount of packets. The ct ASSURED flag is
designed to filter short-lived connections for early expiration.

Offload connections when they are ESTABLISHED and ASSURED.
