The code previously treated all supported request as 'get' actions and
ignored the actual action field in the message. This commit makes the
code look at the action field when processing the requests.

Reforming the data structure in this way will greatly simplify the
implementation of the management message for this data set.

The phyter offers one step sync transmission, but it alters the UDP
checksum by changing the last two bytes, after the PTP payload. While this
is only standardized for IPv6, we will go with it for IPv4 as well, since
the phyter is the only hardware out there.

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.

We use the PTP_SYS_OFFSET ioctl method in preference to doing
clock_gettime from user space, the assumption being that the kernel space
measurement will always be more accurate.

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.
