When large number of port channels (more than 64) is configured, a config reload command might ends with not all port channel configured and up. Further debug shows that unloading the port channels on the ASIC driver take a lot of time. With the change, deleting all port channels before the syncd restart will free resources better and the ASIC driver will unload all netdev fast and the operation will execute properly.
