I have the following setting in which a client that resides on the same
physical network as a server wants to receive any UDP packet that
arrives on any of its interfaces sent by that server.

It's dead easy to transmit and receive multicast traffic, broadcasting
network traffic is so 1980's :)
there is only a difference between multicast and broadcast traffic if you
are spanning subnets.
only the kernel can tell if it is interested in it or not. With
multicast the NIC is configured to only pass particular
Ethernet multicast packets up to the kernel.
By using broadcast traffic the load (okay, hardly a big problem
now-a-days) hits *all* the workstations on the subnet, with multicast,
only those interested in the traffic receive it.
