/*The RFC 3315 says

	Because of the risk of denial of service attacks against DHCP

   clients, the use of a security mechanism is mandated in Reconfigure

   messages.  The server MUST use DHCP authentication in the Reconfigure

   message.

   The following macro enables DHCP client to accept Reconfigure even though

	we don't support authentication yet

	The macro should be removed once we have authentication sorted out
