want ip identification enabled

[Xinwen - Fu]

Hi,
	Now I get that on some OS, for UDP and ICMP packets, the ip
identification fields are not set. 

	But I want that every packet has an id. Is there any emthod to get
the current system glocal variable "ip_id" and change it or 
enable UDP and ICMP ip identification number somewhere?

	Thanks!
