Ken ICHIKAWA 306f83e7b1 Add support for more strict config value validation
This patch adds functions to get int, uint, double value from string
with error checking and range specification.
These functions don't allow overflow and outside of the range values.

In addition, it adds parser_result cases "MALFORMED" and "OUT_OF_RANGE" to make
reason of parse error more clear.

Jacob Keller 76e10e95fb ptp4l: Use poll() instead of a try-again loop
This patch modifies sk_receive in order to use poll() on POLLERR instead of the
tryagain loop as this resolves issues with drivers who do not return timestamps
quickly enough. It also resolves the issue of wasting time repeating every
microsecond. It lets the kernel sleep our application until the data or timeout arrives.

This change also replaces the old tx_timestamp_retries config value with
tx_timestamp_timeout specified in milliseconds (the smallest length of time poll
accepts). This does have the side effect of increasing the minimum delay before
missing a timestamp by up to 1ms, but the poll should return sooner in the
normal case where a packet timestamp was not dropped.

This change vastly improves some devices and cleans the code up by simplifying a
race condition window due to drivers returning tx timestamp on the error queue.

[ RC - removed the unused 'try_again' variable. ]

Delio Brignoli da594e78d9 Make the fault reset interval a per-port configuration parameter.
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. ]

Richard Cochran b96e73994b Support one step sync operation.
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.

Jacob Keller 004b62d22b sk: change sk_interface_phc to sk_get_ts_info
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.

Jacob Keller b8160f2760 ptp4l: add maximum offset to pi servo
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.
