Add Rx adapter support. The event helper init routine will initialize the Rx adapter according to the configuration. If Rx adapter config is not present it will generate a default config. If there are enough event queues available it will map eth ports and event queues 1:1 (one eth port will be connected to one event queue). Otherwise it will map all eth ports to one event queue.
