packets and according to Gratuitous Address Resolution Protocol (GARP)

messages.

Valid options include:

[0] = nothing is changed.

[1] = If the gateway receives RTP packets with a different source MAC

address (than the MAC address of the transmitted RTP packets), then it

sends RTP packets to this MAC address and removes this IP entry from the

address of the transmitted RTP packets.

[3] = both 1 and 2 options above are used (default).
