Enables proxy ARP. When proxy ARP is enabled, the WX replies to ARP
requests for client IP address on behalf of the clients. This feature reduces
broadcast overhead on a service profile's SSID by eliminating ARP
broadcasts from MAP radios to the SSID's clients.
If the ARP request is for a client whose IP address the WX does not
already know, the WX allows MAP radios to send the ARP request to
clients. If the no-broadcast mode is also enabled, the MAP radios send
the ARP request as a unicast to only the clients whose addresses the WX
does not know. However, if no-broadcast mode is disabled, the MAP
radios sends the ARP request as a broadcast to all clients on the SSID.
