Currently the clockIdentity is generated from the mac address of the first
interface/port in config file. This patch add the possibility to set it in
config file.
The reason is if the stack is restarted with a different set of ports, it
may be circumstances when clockIdentity needs to be equal as before
restart even if the port setup is different.

Add attribute maxStepsRemoved which is included in IEEE1588-2017 (v2.1)
It is an optional attribute which can decide if an Announce message is
considered in the operation of the BMCA or not.

Add global option for the hardware time stamp setting.
The function could:
Normally set the filters as the PTP daemon require.
Check that the filters are proper but do not change them.
Full, set the RX filter to all and the TX filter as the PTP daemon require.
[ RC: added missing extern keyword and fixed indentation. ]

This patch adds configuration file support for a table of unicast
masters. Each table lives in its own section and has a unique,
positive numerical ID. Entries in the table are a pair of transport
type and protocol address.
Each port may specify a table id to be used for unicast negotiation.
Tables may not be shared between ports, but nothing prevents table
entries from appearing in more than table.

According to 1588, PTP message loops are simply someone else's problem
with respect to transparent clocks. Since we are running the BMCA for
syntonization anyway, we might as well go ahead and implement the spanning
tree for PTP messages.

This patch adds a new configuation option that enables transparent
clock mode. When TC mode is specified, the configured delay mechanism
must also match. The legacy behavior of upgrading a multi-port clock
from OC to BC is preserved.

When masterOnly is true, the port always returns NULL when computing
its best foreign master. As a result, the port will never enter the
SLAVE state, and the clock will ignore Announce messages received on
that port.
This attribute is specifically called out in G.8275.1 and G.8275.2,
and it is implied by the "master only" mode G.8265.1. In addition,
this option will probably appear in the next revision of IEEE 1588.

Up until now, one step operation was controlled by a combination of
options, namely time_stamping=hardware with twoStepFlag=0. The
introduction of peer to peer one step makes the situation a bit more
complicated.
This patch adds support for setting the one step options directly by
using the "time_stamping" option. The "twoStepFlag" is adjusted
automatically if needed. The legacy behavior for Sync message one
step is preserved.

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.

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.

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.
