Good point, yes, I also think that should be fixed.

Currently seems only LWIP_NSC_IPV4_ADDRESS_CHANGED check if the
setting is actually being changed.

When enable LWIP_NETIF_EXT_STATUS_CALLBACK:
I got below event every time when dhcp server re-assigned ip address even the gateway/netmask/ip are exactly the same with previous setting.

LWIP_NSC_IPV4_GATEWAY_CHANGED
LWIP_NSC_IPV4_NETMASK_CHANGED
LWIP_NSC_IPV4_SETTINGS_CHANGED

I think these callbacks should be called only when the
setting is actually being changed.
