 My apologies for the multiple screwed-up mailings of this patch!  Here is the
 proper patch correctly formatted.
 
 Here is a corrected patch for this problem.  In a default installation
 with IPv6 enabled, there will be attempts by both IPv4 and IPv6 to
 bring up plip[012].  The patch to rc.d/network_ipv6 detects when
 ipv6_ifconfig_plipn is set to NOAUTO.  The patch to defaults/rc.conf
 sets both ifconfig_plip[012] and ipv6_ifconfig_plip[012] to NOAUTO,
 keeping the plip interfaces from being brought UP automatically.
