This fixes an issue with free running clocks. When the master clock id
changes the measured master/local ratio should be reset. If it isn't,
and the local clock becomes master, then the last measured ratio to
the old master continues to be used in peer delay calculations. If a
bad master/local ration calculation triggers this state change the
port can get "stuck" in not "asCapable" mode.

mc6_addr holds the parsed multicast address to which messages should be sent.
But since each port can have a different scope, and the primary MC address
depends on the scope, it really can't be stored in a global variable. Move both

Users may need to use different socket priorities for ptp4l traffic for
the purpose of traffic shaping. An example is to route ptp4l traffic
through a specific Linux egress queue using the mqprio qdisc.
- Update raw.c open_socket() to accept a socket_priority parameter
- Add the socket_priority option to config.c and the default.cfg config
file. The option defaults to 0.

Add provision to disable delay requests. Designated masters who do not
need to calculate pdelay can use this option. This is required by
Automotive Profile to reduce network load.
Signed-off-by: Vedang Patel <vedang.patel@intel.com>
This commit adds functionality to increase the sync and pdelay request
intervals once gptp synchronization has been achieved. This is useful
while running Automotive Profile where the network is usually static.
Here, we are assuming that the gPTP synchronization is achieved whenever
the last 'n' offsets calculated using the Sync messages are below a
certain threshold. Both, the number of offsets to consider and the offset
threshold are configurable.
In order to support the interval update, a new clock servo state
CLOCK_SERVO_STABLE has been added. The clock will transition to this
state whenever the above condition is satisfied. When this transition
occurs, the slave will send an "interval request" signaling message
asking the master to change the sync interval. It will also update the
pdelay request interval locally.
Four new config options have been added to provide this functionality:
- servo_offset_threshold: All the offset values being considered should
be below this value.
- servo_num_offset_values: number of previously received offset values
to consider.
- operLogSyncInterval: slave will ask the master to switch to this
interval for sending sync messages when the offset stabilizes.
- operLogPdelayReqInterval: the slave will set this interval for pdelay
request messages when the offset stabilizes.
