Jiri Benc 648197153e clock: event notification
Split management message creation to more fine-grained functions to allow
notification messages to be created.

The new clock_management_fill_response is called from
clock_management_get_response (so the function behaves exactly the same as
before this patch) and from a new clock_notify_event function. The
difference is clock_management_get_response uses the request message to
construct the reply message, while clock_notify_event constructs the reply
message based on the notification id.

Miroslav Lichvar 61de819d56 Include clock rate ratio in delay calculation.
With the new linreg servo the frequency offset and time offset are
controlled separately. The ratio between master's frequency and the
current frequency of the local clock is known and can be used when
calculating delay or peer delay to improve their accuracy.

This greatly improves the stability of the delay when the servo is
correcting a large offset.

Miroslav Lichvar ed379b4028 Add clock sanity check.
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.

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

Jacob Keller 0499513f1e ptp4l: remove timestamping as a per-port configuration option
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.

Jacob Keller 0afedd7993 ptp4l: use ethtool operation to double check PHC
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.
