Specifying a padding mode for the Interface-ID option

This feature enables the relay agent to fill the Interface-ID option in the specified mode. When receiving a DHCPv6 packet from a client, the relay agent fills the Interface-ID option in the mode and then forwards the packet to the DHCPv6 server.

3. Specify a padding mode for the Interface-ID option.
