(MAC) address equal to the proxied BTS MAC address

C. The iPipe blocks multicast and broadcast frames at the Ethernet SAP ingress and only forwards
unicast payloads to the BTS

D. The iPipe SAP sends an Address Resolution Protocol (ARP) request for the BTS's MAC address and
forwards the frame with the BTS destination MAC address
