From 572772cf7ccf3f3860c0121c89ee22e0001d0692 Mon Sep 17 00:00:00 2001
From: Christopher Pascoe <pascoe@cvs.openbsd.org>
Date: Sun, 31 Jul 2005 03:30:56 +0000
Subject: Change the API for icmp_do_error so that it takes the mtu directly,
 rather than a pointer to struct ifnet containing it.

Saves a 448 byte stack allocation in ip_forward which previously faked up
a struct ifnet just for this purpose.
