AFAIU, you are adding the sysctl to close a very short period
of time between cloning a lagg(4) and configuring it.
This is not a pretty solution to the problem. But the network
stack has an API for supplying extra parameters at the cloning
time. The lagg_clone_create() accepts the params, that can
be supplied by ifconfig. If you put there the same arguments you
supply with SIOCGLAGGOPTS, you can create and configure a lagg
in one syscall.
