While this certainly improves the situation, I'm still able to trigger an assertion (`sys/net/gnrc/network_layer/ipv6/nib/_nib-internal.c:289 => 0x5657b821`) with:
```
nib prefix add 65542 2001:db8::/64
```
with a  gnrc_networking instance on native. The interface number here is 6+65536. Checking if the supplied number is between the bounds of a `kernel_pid_t` should fix this.
