There is no way to determine if the remote processor has observed a message,
that does not involve pretty trivial race conditions.

Thanks for chiming in.
How is it supposed to work if a client queues more than one request?
How do you know when it's ok to overwrite the FIFO and send the next
command?
  Usually if h/w doesn't indicate, we cook up some ack packet for each
command. Otherwise the protocol seems badly broken.

 If there is really nothing that can be done to check delivery of a
message, I'll pick the driver as such. Best of luck :)
