I can't speak for iperf3, but I'm doubtful there is a way to do this with iperf
2 <https://sourceforge.net/projects/iperf2/> because the network stack's
routing table is going make the forwarding decisions and it won't send
things out that our destined to self.
What platform are you using? If using linux, one may be able to code up an
AF_PACKET socket to do this
<http://www.microhowto.info/howto/send_an_arbitrary_ethernet_frame_using_an_af_packet_socket_in_c.html>.
Iperf 2 supports AF_PACKET receives in order to do l2tests.
