services.strongswan-swanctl.swanctl.connections.<name>.children.<name>.if_id_out
XFRM interface ID set on outbound policies/SA. This allows installing
duplicate policies/SAs and associates them with an interface with the
same ID. The special value %unique sets a unique
interface ID on each CHILD_SA instance, beyond that the value
%unique-dir assigns a different unique interface ID
for each CHILD_SA direction (in/out).
The daemon will not install routes for CHILD_SAs that have this option set.
