commit 7e8eba5332671abfd95d06dd191059eded1d2cca

clock: Reset state when switching port with same best clock.
When the best port is changed, but the ID of the best clock doesn't
change (e.g. a passive port is activated on link failure), reset the
current delay and other master/link-specific state to avoid the switch
throwing the clock off.

clock: Reset clock check on best clock/port change.
Reset the clock check when the best clock or port changes, together with
the other state like current estimated delay and frequency. This avoids
false positives if the clock is controlled by an external process when
not synchronized by PTP (e.g. phc2sys -rr).

port: Don't check timestamps from non-slave ports.
Don't perform the sanity check on receive timestamps from ports in
non-slave states to avoid false positives in the jbod mode, where
the timestamps can be generated by different clocks.

commit 6df84259647757bc53818a039734f8ff85618c02

port: Don't renew raw transport.
Renewing of the transport on announce/sync timeout is needed in the
client-only mode to avoid getting stuck with a broken multicast socket
when the link goes down.
This shouldn't be necessary with the raw transport. Closing and binding
of raw sockets can apparently be so slow that it triggers a false
positive in the clock check.

clockcheck: Increase minimum interval.
Increase the minimum check interval to 1 second to measure the frequency
offset more accurately and with default configuration make false
positives less likely due to a heavily overloaded system.
