Up until now the transportSpecific field has been treated according to
802.1AS, namely as a field that must match exactly on receive.
However, 1588 mandates ignoring this field for some transports, and
there is equipment in the wild that does in fact set the reserved
bits.
This patch adds an option to ignore the field on receive completely.

This option allows the clock to be updated before the path delay is
measured in order to speed up the initial correction of the clock, e.g.
in domains using a very long logMinDelayReqInterval.

Now the ts label will be either the bond active slave or the interface
name, which is the exactly interface we need to get ts info.
When the link down/up or there is a fail over and ts_label changed, the
phc index may also changed. So we need to check get new ts info and check
clock_required_modes. We will set the link to LINK_DOWN by force if
the new ts_label's timestamp do not support required mode.
If all good, then we set phc index to new one. Also sync clock interval
after switch phc.

When running multiple instances of ptp4l or phc2sys, it's difficult to
tell which log message belongs to which instance. Add new options to
ptp4l and phc2sys which can specify a tag for all messages printed to
the standard output or system log, so messages from different instances
can have different tags.

Currently UTC offset is defined as a constant - CURRENT_UTC_OFFSET, and if
a leap second is added, that constant is no longer valid. Ptp4l was
updated to read the UTC offset from configuration instead.

The recent change allowing every configuration option to appear on the
command line wrongly used bitwise AND to set a flag. This patch fixes
the bug by using the proper bitwise OR idiom.

Fixes: 4e8dbd8 ("ptp4l: Accept any configuration option as a command line argument.")
This patch provides a way to use the entire table of configuration options
as "long" command line switches.

In the last years there are several media streaming standards
evolving that are relying on PTP. These standards make requirements
about the DSCP priority of PTP messages. This patch introduces two
new configuration options 'dscp_event' and 'dscp_general' to address
that issue and to be able to set the DSCP priority separately for
PTP event messages and PTP general messages.

There is no need to have a function to get this information as
we can easily obtain it when the interface is first created.

The draft Enterprise Profile [1] specifies a hybrid E2E delay mechanism,
where the delay response message is sent "in kind". That is, if the
request is unicast, then the response is also unicast. Apparently this
scheme is already in widespread use in some industries. Also, it makes
sense, because those messages are of no interest to the other slaves in
the PTP network.
Because of the address work already in place, in turns out that adding
this mode is almost trivial. This patch introduces an "hybrid_e2e" option
that enabled the new mode.

Now that all of the legacy, open coded configuration fields are gone,
we can follow a normal create/destroy pattern for the configuration.
This patch add the new method and converts the programs to use it.

Now that all of the legacy parsing code is gone, there remain two

Global default values will be static strings, but values from the
configuration file will be dynamic, so the code remembers whether or it

This conversion is not straightforward due to the fact that these options
can take a value of "ASAP" or a number. We check for the special ASAP
case in a helper function and leave the numbers to the generic code.
