>Environment:
System: FreeBSD scone.ki.iif.hu 5.3-STABLE FreeBSD 5.3-STABLE #5: Thu Nov 11 05:45:29 CET 2004 root@scone.ki.iif.hu:/usr/obj/usr/src/sys/SCONE i386

>Description:
	tcpdumps dumps core on the ip6cp packets. On FreeBSD 5.3 the ip6cp packet dumps core while on FreeBSD 4.9 says:
	07:34:56.393507 PPPoE  [ses 0xddfb]

	FreeBSD 5.3 uses: tcpdump 3.8.3
	FreeBSD 4.9 uses: tcpdump 3.7.2

	probably this has been already reported in pr=71453

>How-To-Repeat:
	Try to read into the tcpdump the attached uuencoded ip6cp packet.


begin 644 ip6cp_packet
MU,.RH0(`!````````````/__```!````$%'O02,!!@`\````/``````"/SM!
M^@`*0DOL'(AD$0#=^P`0@%<!`0`.`0H``````````0``````````````````
*````````````````
`
end

>Fix:
Import basic ipv6cp support from: 
http://cvs.tcpdump.org/cgi-bin/cvsweb/tcpdump/print-ppp.c?r1=1.102&r2=1.103
