The issue happens on every port initialization, but as the ports are expected to move quickly to DISTRIBUTING, it doesn't cause much problem. However, it does cause constant packet loss if the other peer has the port configured to stay in STANDBY (i.e. SYNC set to OFF). Signed-off-by: Flavio Leitner Signed-off-by: David S.
