From bd9a6a7bd8883c607a3a41ff3d7a340ae6ae1a1b Mon Sep 17 00:00:00 2001
From: gpalmer <gpalmer@FreeBSD.org>
Date: Wed, 12 Jun 1996 19:24:03 +0000
Subject: Since the updates to ifnet.if_lastchange are so rare (relatively
 speaking), go for the extra accuracy and call microtime() to get the current
 time.
