RFC states that broadcast flag should be set,
A client that cannot receive unicast IP datagrams until its protocol
software has been configured with an IP address SHOULD set the

receive unicast IP datagrams before its protocol software has been
configured SHOULD clear the BROADCAST bit to 0. The BOOTP
clarifications document discusses the ramifications of the use of the
However we could add a workaround, when DHCP client will switch off broadcast after 15 sec of not getting the address;
- 15sec broadcast;
- 15sec without broadcast, when broadcast messages fail.
