commit: https://git.buildroot.net/buildroot/commit/?id=09f1b8011b580ae4ce21b6f0e716d69b86efa26a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
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.
