PTP-notification was treating clockClass values 7 and 135 as indicators of a locked status, which is incorrect as per ITU-T G.8275.1. This was resulting in ptp-notification delivering locked status to clients when it should instead be transitioning to holdover/freerun. Removed clockClass 7 and 135 from the list of valid locked clockClasses. PTP-notification is now able to properly transition states when these classes are observed. Test plan: PASS: Build and deploy image PASS: Verify correct state transitions when clockClass 6, 7, 135 are observed Partial-Bug: 1995014 Signed-off-by: Cole Walker <cole.walker@windriver.com> Change-Id: If68df991c3d6555f09e19a0d11f2c71e077c2587
