From 09f1b8011b580ae4ce21b6f0e716d69b86efa26a Mon Sep 17 00:00:00 2001 From: Petr Kulhavy Date: Wed, 7 Jun 2017 20:44:29 +0200 Subject: [PATCH] linuxptp: new package Add the Linux PTP Project package. http://linuxptp.sourceforge.net/ The SysV and systemd init scripts start the daemon in slave-only mode on eth0 and synchronize the system clock to PTP.
