netifd Call Flow - WiFi

[Ravi Paluri (QUIC)]

Hi All,
      We are trying netifd to enable wlan.
We have configured uci to set wlan interface IP statically.
We are seeing when we do network reload, wifi interface is going down and coming up.

Can we get flow how does netifd know that wifi interface is up and where it adds this IP to the interface?
This will help us in checking why wifi interface is going down and coming up on doing network reload.

Thanks,
Ravi
