Just to add on it, I have done changes in DHCP Relay.
Any one knows, which part of code, I can look if I want to see that on which interfaces we are looking for Broadcast packets ?

Hi All,

I am dynamically adding and removing interfaces in DHCPv4 using same logic written in discover_interfaces.
Everything works fine, but as soon as I move my logic of adding and removing interfaces into a thread, those interfaces are not listening for broadcast packets, but they are able to process unicast packets.

Anyone have any idea what can be the reason ? And clue will be really appreciated.
