Eth Hal will configure interface and monitor the link. CcspEthAgent will subscribe for ‘EthInterfaceStatus’ event so that it can receive the notification form Vendor Software (i.e. Eth Hal)whenever physical link event change.
JSON HAL server library can be used by the vendor application to receive actions from RDK WanManager application and do necessary action. The vendor application that has HAL server library integrated will receive the JSON rpc request from the RDK WanManager, process the request and sends the JSON based response back to the RDK WanManager. The HAL server also helps to dispatch asynchronous events to the RDK WanManager based on the event subscription.
