Jim Somerville 8445cd91a1 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.

Subject: [PATCH 1/6] 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.
