Subject: timesync: IPTOS_LOWDELAY --> IPTOS_DSCP_EF
X-Git-Tag: v256-rc1~1238
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aafaafb6f725e145192d95ef740714f0339b1252;p=thirdparty%2Fsystemd.git

timesync: IPTOS_LOWDELAY --> IPTOS_DSCP_EF

Deprecated IPTOS_LOWDELAY is ignored by most of today's
network equipment that only ever care about DSCP.

Use the DSCP found in other NTP implementations and set the appropiate
TCLASS for IPv6.
