Actually is is documented, see man ettercap:
-u, --unoffensive
Every time ettercap starts, it disables ip forwarding in the kernel and
begins to forward packets itself. This option prevent to do that, so the
responsibility of ip forward‐ ing is left to the kernel.
On top of that, ettercap is designed for man in the middle attacks, disabling
kernel forwarding seems to be a must.
man ettercap:
