Application as Server
The host application has to register with the netX firmware in order to receive indication packets.
Depending on the protocol stack, this is done either implicitly or explicitly (if application wants to
receive unsolicited DPV1 packets). Details on when and how to register for certain events is
described in the protocol specific manual.
When an appropriate event occurs and the host application is registered to receive such a
notification, the netX firmware passes an indication packet through the mailbox (transition 1  2).
The host application is expected to send a response packet back to the netX firmware (transition 3
 4).
