>
> IEEE1588 forwarding mode uses same port to receive and transmit packets.
> In this mode, the MAC address in the packets are not touched, and
> therefore, packets could be sent with the same destination MAC address as
> the MAC address of the port that is transmitting, which causes the packet
> to be dropped in some NICs.
>
> In order to avoid this scenario, MAC addresses are swapped before packet
> is sent out.
