- print-telnet.c: do not print control character
- print-icmp6.c: improve icmp6 node information printing
(we need to at least meet our kernel code!)
- update dhcp6 printing to 15 draft (14 and 15 are totally incompatible)
- add safeputc() and safeputs() into util.c
- more length overflow check for ip6 related parsing
- protocol decode fixes
- add dhcp6 parser
XXX how should we maintain usr.sbin/tcpdump for years to come?
relationship with www.tcpdump.org codebase?
