In order to set the scope id, we will need to know the interface index
before sending, in some cases.

It is safer and more correct to clear the addresses before use. The IPv6
fields flowinfo and scope_id in particular should not be set to random
values from the stack.

this patch uses the new sk_get_ts_info data to check whether the selected
timestamping mode is supported on all ports. This check is not run if the port
data isn't valid, so it will only fail if the IOCTL is supported. This allows
for support of old kernels that do not support the IOCTL to still work as expected.

this patch changes sk_interface_phc to sk_get_ts_info, by allowing the function
to store all the data returned by Ethtool's get_ts_info IOCTL in a struct. A new
struct "sk_ts_info" contains the same data as well as a field for specifying the
structure as valid (in order to support old kernels without the IOCTL). The
valid field should be set only when the IOCTL successfully populates the fields.
A follow-on patch will add new functionality possible because of these
changes. This patch only updates the programs which use the call to perform the
minimum they already do, using the new interface.

It seems with some cards the current default of 2 is too small, increase
the number to prevent users from having to investigate the EAGAIN error
messages.

Now that the code automatically falls back to transport-specific time
stamping, this option is no longer needed.

Start with the most general HWTSTAMP option. If that fails, fall back
to the option that best fits the interface's transport.

this patch modifies the pi servo to add a configurable max offset (default
infinity). When ever the detected offset is larger than this value, the clock
will jump and reset the servo state. The value of this feature is for decreasing
time to stabalize when clock is off by a large ammount during late running. This
can occur when the upstream master changes, or when the clock is reset due to
outside forces. The method used to reset clock is simply to reset the pi servo
to the unlocked state.

passing a string as the servo type seems ugly when there are only a few
choices. This patch modifies the servo_create to take an enum instead.

The main loop has become a bit messy, mixing two completely disjunct code

This non-portable, implementation specific message is designed to inform
external programs about the relationship between the local clock and the
remote master clock.
Signed-off-by: Richard Cochran <richardcochran@gmail.com>
The code to detect a new master used pointer equality using a stale
pointer within the clock instance. Instead, the clock needs to remember
the identity of the foreign master in order to correctly detect a
change of master.
