Description Unicorn 2001-03-13 01:20:00 UTC 
	When ip_output called within dummynet guts it takes
	cooked mbuf ready to be sent. In ip_output() local variable 
	`struct in_ifaddr *ia' is used to evaluate outgoing i-face counters, 
	but left uninitialized. (see compiller worning)

	In previous snaps this bug don't crash system. But
	dummynet hangs sometimes for the same reason.. I guess.

How-To-Repeat: 	Send packet matches pipe rule.

This has been fixed already in revision 1.123 of ip_output.c, with 
a patch that is almost identical to yours. Thanks anyway for the 
bug report!
