[Anoob] Will fix in v2.

[Anoob] The member, "mode_params" is the opaque pointer which is used internally. There are two fields which need to be communicated between application and helper library.

1. mode: whether the application is running in event-mode or poll-mode. Both application and helper library would need this. This field is set by the helper while parsing the eventmode args.
2. eth_portmask: helper library needs this info from application to know which all ethernet ports it can use. This is determined by the application and has to be communicated to the helper library. This can be made as params passed to the application, but eth_portmask will be the only member in it, as of now.

With the above use case, do you recommend any different structure layout?
