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.

The Linux PTP Project is the Precision Time Protocol
|
||||||
|
implementation according to IEEE standard 1588 for Linux.
|
||||||
|
|
||||||
|
The dual design goals are to provide a robust implementation
|
||||||
|
of the standard and to use the most relevant and modern
|
||||||
|
Application Programming Interfaces (API) offered by the
|
||||||
|
Linux kernel. Supporting legacy APIs and other platforms is
|
||||||
|
not a goal.
