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.

This patch adds support for sk_interface_phc to lookup the /dev/ptpX device
using ethtool's get_ts_info ioctl
-v2-
* set ethdev to null initially
* rebased on top of phc2sys changes
-v3-
* fixed typo regarding slash

The main loop has become a bit messy, mixing two completely disjunct code
paths. This patch separates the two use cases for the sake of clarity.

This non-portable, implementation specific message is designed to inform
external programs about the relationship between the local clock and the
remote master clock.

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.
