Is there anything similar between them ?
The tunnel device allows a user-land program to read and write
packets from and to a pseudo network interface.
A divert socket allows the redirection of packets from the kernel to
a user-level program and back - based on any firewall type criteria.
We *need* them both so that we can write smart user-level programs.
More than a few people would argue that neither are needed - they
just encourage hacking.
