That works for me. I notice that we already specify this for the Write
RPC:
If the Write is attempted before a ForwardingPipelineConfig has been set, the server must return a FAILED_PRECONDITION error.
My current implementation of P4Runtime already enforces that behavior: https://github.com/p4lang/PI/blob/970a2f254bf0aa5bc5366f815d7e8f0f0df789f2/proto/server/pi_server.cpp#L435
Do you want to submit a PR @stefanheule?
I believe the P4RT spec says nothing about the behavior of the switch for Read if there is no P4Info configured yet. We should clearly specify the desired behavior. I suggest we return FAILED_PRECONDITION, since reading table entries requires to know what tables there are.
