[ntp:questions] QoS always the same Freebsd 6.1 ntpd 4.2.5p135 at 1.1793-o

I would like NTP traffic to use my providers EF traffic class. One way of
doing that would be to send packet with DSCP == 46 (TOS byte == 184).
But I have had no luck.

I have fetched latest dev version (4.2.5p135 at 1.1793-o)

No matter if what i try to configure(nothing, qos lowdelay, qos throughput,
qos cs5) the packet get send with tos==0xc0.
Trying to configure "qos 184" triggers a error in log:
Oct  2 13:41:00 hjj ntpd[65100]: syntax error, unexpected T_Integer, expecting T_String
Oct  2 13:41:00 hjj ntpd[65100]: parse error /etc/ntp.conf line 22 ignored
so I am confident that the qos line can be read.

Is that a problem specific to 4.2.5p135 at 1.1793-o?
Is it a FreeBSD problem? (Do it work on other platforms?)

I have been trying to read the code. I have not been able to figure out where
"CONF_QOS_*" gets translated to the actual values. A pointer please.

It looks as "EF"(http://www.iana.org/assignments/dscp-registry/) is not one of
the supported values. I am missing that value. Or a possibility to specify any
