socketif: dummy implementation of pa_routerif_register_implicit_connection()
socketif: dummy implementation of pa_routerif_register_implicit_connection()

I don't know what the function is supposed to do, but
pa_routerif_register_implicit_connections() already has a dummy
implementation, so maybe a dummy implementation for
pa_routerif_register_implicit_connection() is fine too. Without this
I get a linker error about an undefined reference.
