Richard Cochran 1bdc9143aa Introduce the ts2phc program.
Some PTP Hardware Clocks have input pins that can generate time stamps
on the edges of external signals.  This functionality can be used in
various ways.  For example, one can synchronize a PHC device to a
global time source by taking a Pulse Per Second signal from the source
into the PHC.  This patch adds support for synchronizing one or more
PHC slaves to a given master clock.

The implementation follows a modular design that allows adding
different kinds of master clocks in the future.  This patch starts off
with a single "generic" PPS master, meaning a PPS signal that lacks
and time or date information.  The generic master assumes that the
Linux system time is approximately correct (by NTP or RTC for example)
in order to calculate the time of the incoming PPS edges.

Anders Selhammer b2f2c9e02d snmp4lptp: Add snmp sub agent for linuxptp
The sub agent use net-snmp library and AgentX protocol for the
communication towards the snmp master agent.
snmpd.c should only include general setup needed for handling snmp.
Supported MIBs should be implemented in separate files.
Makefile will include snmpd if libsnmp is available during compilation.
configs/snmpd.conf should be placed in /etc/snmp/

Richard Cochran ab8dc20cf7 nsm: Implement the NetSync Monitor query.
This patch adds a new "NSM" program.  The new code handles only one
outstanding NSM command at a time.  If and when all four event time
stamps have arrived, the code prints the instantaneous estimated
offset without any averaging or smoothing.

Jacob Keller bdb6a35883 linuxptp: add phc_ctl program to help debug PHC devices
This is an updated version of a script I wrote a couple years ago for
debugging the PHC when writing a new driver. I figured that it might be
handy for the LinuxPTP project to include, as it can give some insight
into the PHC directly. I have updated it to make use of the shared code
here, in order to reduce duplication. Hopefully this is of some use to
everyone.
