ACX5448/ACX710: Ethernet oam CCM not sent from the configured interface if it has hierarchical scheduler.

With the following configuration if AE50 has hierarchical scheduler the OAM packets will not be sent out.

    connectivity-fault-management {
        inactive: performance-monitoring {
            delegate-server-processing;

            }
        }
        inactive: maintenance-domain test {

            maintenance-association ma {
                continuity-check {
                    interval 1s;
                }
                mep 1 {
                    interface ae99.10;
                    direction down;
                    auto-discovery;
                }
            }
        }
    }
}

This is a product limitation and not currently supported. Remove hierarchical scheduler from the interface if OAM CCM must be used.
