: name of remote service that is published
struct rpmsg_ns_msg - dynamic name service announcement message @addr: address of remote service that is published @flags: indicates whether service is created or destroyed This message is sent across to publish a new service, or announce about its removal. When we receive these messages, an appropriate rpmsg channel (i.e device) is created/destroyed. In turn, the ->probe() or ->remove() handler of the appropriate rpmsg driver will be invoked (if/as-soon-as one is registered).
