An squeue belongs to exactly one netstack.  A netstack may have one or

I don't think that is the case. In fact tcp.c has:
 * This list is per squeue and squeues are shared across the tcp_stack_t's.

The motivation is that the number of squeues should be related to the number of CPUs to get good scalability, while the netstacks is a logical construct for the exclusive-IP zones. Hence with 100 exclusive-IP zones it doesn't make sense to have 100 squeues on a 8 CPU/core system.
