From 7c43d431173a73617c079b7945b6629daaa7bca0 Mon Sep 17 00:00:00 2001 From: Codarren Velvindron Date: Sun, 15 Apr 2018 20:37:50 +0400 Subject: ntpd: deprecate IPTOS_LOWDELAY in favor of IPTOS_DSCP_AF21 Update QoS markers. Use DSCP AF21 for interactive traffic. DSCP is defined in RFC2474. Many modern equipment no longer support IPTOS.
