Thank you Peter and Hunter.

The client is innocent. I used tcpdump and Wireshark to find that client generates valid unicast renew with CIADDR value set. So now I need to find what device modifies the request - Wi-Fi bridge or access point. To achieve this I need to sniff and decrypt Wi-Fi traffic.
