Check the sanity of the synchronized clock by comparing its uncorrected
frequency with the system monotonic clock. When the measured frequency
offset is larger than the value of the sanity_freq_limit option (20% by
default), a warning message will be printed and the servo will be reset.
Setting the option to zero disables the check.
This is useful to detect when the clock is broken or adjusted by another
program.

Management messages can cause a change in the clock quality. If this
happens, then it is time to run the Best Master Clock algorithm again.

New clock options should go into 'struct default_ds' so that we can avoid
growing clock_create indefinitely.

Add new options to ptp4l and phc2sys to print summary statistics of the
clock instead of the individual samples.
[ RC - Fix () function prototype with (void).
- Use unsigned for sample counter.
- Fix over-zealous line breaks. ]

Adds struct containing clock description info that will be needed for
USER_DESCRIPTION and CLOCK_DESCRIPTION management messages.

Reforming the data structure in this way will greatly simplify the
implementation of the management message for this data set.

this patch allows each port to maintain its own pod structure since it is only
used in ports. This will allow the user to configure any special settings per
port. It takes a copy of the default pod, and a future patch will allow the
configuration file to set per-port specific changes

this patch modifies the ptp4l.c and config settings so that the iface list is
inside the cfg_settings structure

* Moved "struct interface" into config.h

The current code for the timestamping mode does not allow interfaces to have
separate timestamping modes. This is (probably) due to hardware timestamping
mode being required on all ports to work properly.
This patch removes the timestamping field in the struct iface, and makes it a
clock variable which is really what the mode does anyways. Ports get passed
the timestamping mode but no longer appear as though they are separate.

This commit only adds support for forwarding the management messages.
The actual local effects of the management commands still need to be
implemented.

If the new ethtool operation is supported, then use it to verify that the PHC
selected by the user is correct. If the user doesn't specify a PHC and ethtool
is supported then automatically select the PHC device.
If the user specifies a PHC device, and the ethtool operation is suppported,
automatically confirm that the PHC device requested is correct. This check is
performed for all ports, in order to verify that a boundary clock setup is
valid.
The check for PHC device validity is not done in the transport because the
only thing necessary for performing the check is the port name. Handled this
in the port_open code instead.

Since the master implementation is still lacking, we will just keep
the slave-only flag hard coded for now.

This commit also introduces clock and port objects, but only with the
minimal interface needed by the BMC.
