Uprev linuxptp to version 3.1.1-1

We use the CentOS 8 version of the source package
and apply the same six patches that we applied to
the previous version, with one caveat.  Patch 3
had an additional test in it of the uncalibrated
state, and this test does not exist in the upstream
version of the patch.  Now patch 3 is identical
to the upstream version.

All five upstream patches have been refreshed to
what was actually accepted upstream and thus now
contain proper git headers.  The logic of those
five patches remain as they were, with the one
exception noted in the previous paragraph.

Patch 6 has also now been given a proper git header.

+
+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.

+Subject: [PATCH 2/6] 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).

+Subject: [PATCH 4/6] 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.

+
+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.

 Subject: [PATCH 6/6] Add option to disable default port selection in phc2sys
 
+This change serves to address an issue in phc2sys
+where the local ptp clocks are not synced together properly if the local
+time is far behind the reference time. This issue occurs when phc2sys
+starts and there is no client port currently synced to a grandmaster. In
+the original behaviour, phc2sys selects the first configured port and
+proceeds to sync all of the other clocks to it by performing the
+first_step operation.
+
+Then ptp4l will evenually lock to the Grandmaster clock, and that
+single port will have its time updated to the correct value, but
+phc2sys has already performed the first_step operation and will not
+step the other clocks again.
+
+This solution provides an option to disable the selection of a
+default port by phc2sys. When no default port is selected, phc2sys waits
+for ptp4l to sync to the Grandmaster before bringing the other clocks
+into sync with the first_step operation.
+
+This option is configured via the default_sync
+parameter or the -D flag. The default_sync parameter is set to on by
+default in order to keep the behaviour the same as upstream linuxptp
+but can be configured by users via
+system service-parameter-add ptp global default_sync=0
