Product: Wireshark
Version: Git
Hardware: x86-64
OS: Linux
Status: UNCONFIRMED

NTP control Read Ordered List command
Build Information:
v2.5.0rc0-1943-g91548948
--
According to draft RFC draft-ietf-ntp-mode-6-cmds-03 (Control Messages Protocol
for Use with Network Time Protocol Version 4) [1], Opcode 11 should be
dissected as Read Ordered List command. Currently, Wireshark displays Opcode as
Unknown and doesn't dissect returned list of variables. For example, I request
interfaces statistics using ntpq tool:
ntpq> ifstats
interface name send
# address/broadcast drop flag ttl mc received sent failed peers uptime

Thanks.
