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

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 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.

If a buggy driver or hardware delivers bogus time stamps, then we might
crash with a divide by zero exception.

This port is handled a bit differently than the others. Its only purpose
is to accept management messages from the local machine.

this patch allows each port to maintain its own pod structure since it is only
used in ports. This will allow the user to configure any special settings per
port. It takes a copy of the default pod, and a future patch will allow the
configuration file to set per-port specific changes

the port_open function takes a large number of command options, a few of which
are actually all values of struct interface. This patch modifies the port_open
call to take a struct interface value instead of all the other values. This
simplifies the overall work necessary and allows for adding new port
configuration values by appending them to the struct interface

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 commit only adds support for forwarding the management messages.
The actual local effects of the management commands still need to be
implemented.

If an announce timeout occurs on a port, and no other port is slaved, then
the clock must become a grand master by default.

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.

The current port code is very defensive. As the code now stands, we throw
a fault whenever we cannot send or receive a packet. Even a downed link
on an interface will cause a port fault.
This commit adds a very simple minded way of clearing the faults. We just
try to enable the port again after waiting a bit.

It was a cute idea to have the raw Ethernet layer use just one socket,
but it ended up not working on some specific PTP time stamping hardware.
