Porting Profinet IO to Netos7

I’m trying to port/adapt the Profinet IO stack (developed by Siemens) from Netos6.3 to Netos7.3. However, once an IP address has been acquired, I’ve been unable to change the IP address without having to save to NVRAM and reboot. In Netos6.3 the following functions were used to change the IP address: ll_config(), ip_router_advertisements(), and ip_add_static_route(). I could not find any similar functions in Netos7.3

Does anyone have a method of changing the IP address without having to reboot?
