   This might be related to the usage of USRSOCK component.
   
   `netlib` does not perform any validation on the interface name before 
requesting the IP change to the network stack.
   
https://github.com/apache/incubator-nuttx-apps/blob/master/netutils/netlib/netlib_setipv4addr.c#L66
   
   When USRSOCK is enabled, the NuttX netstack is bypassed and the handling of 
the `SIOCSIFADDR` ioctl command is delegated to the USRSOCK daemon, which in 
this case is `gs2200md`.
   So, in the current state, it is up to the device driver connected via 
USRSOCK to do the right processing, similar to what `netdev` does:
   
https://github.com/apache/incubator-nuttx/blob/master/net/netdev/netdev_ioctl.c#L605-L617
   
   So, most probably the issue is that GS2200m is simply setting the IP 
regardless of the interface name being set:
