/*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
