A timeout of 15 seconds is not always acceptable, make it configurable.
By popular consensus, instead of using a linear number of seconds, use
the 2^N format for the time interval, just like the other intervals in
the PTP data sets. In addition to numeric values, let the configuration
file support 'ASAP' to have the fault reset immediately.
[RC - moved the handling of special case tmo=0 and added a break out
of the fd event loop in case the fds have been closed.
- changed the linear seconds option to log second instead.
- changed the commit message to reflect the final version. ]

The Linux kernel supports a hardware time stamping mode that allows
sending a one step sync message. This commit adds support for this mode
by expanding the time stamp type enumeration. In order to enable this
mode, the configuration must specify both hardware time stamping and set
the twoStepFlag to false.
We still do not support the one step peer delay request mechanism since
there is neither kernel nor hardware support for it at this time.

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.

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.

this patch causes interfaces to be built after the options have finished
scanning rather than during option parsing. This removes the ability to

This patch adds a flag field for setting overflag flags so that command line
options override any value in the configuration file. This will be done by
ensuring the flags set whether the config parser accepts the values specified.
This patch also streamlines the handling for the slave only command line
option, as it no longer needs special treatment.

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 patch updates the global set functions to allow the user to set the

feature. The new patch allows the function to specify exactly what they want
the value to be.
This patch also clarifies what -q and -v do by removing mention of quiet mode
and verbose mode. It is easy for a user to confuse and assume that -q disables
-v when this is not true.

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.
