For discussion.

Autofp performance is much lower than workers, and using cluster_flow workers should be available everywhere.

Removing it would allow us to simplify the code as well as get rid of some runtime checks leading to better performance for workers.

We could perhaps automatically fall back to --pcap to provide a smooth upgrade path.

In tpacket-v3 workers is already the only supported mode. So with the removal of tpacket-v1 the only support we have with autofp is tpacket-v2.
