A "delay mode" feature was put in place to work around a problem that was observed during development of the upstream IPA driver. It used TX endpoint "delay mode" in order to prevent transmitting packets toward the modem before it was ready. A race condition that would explain the problem has long since been fixed, and we have concluded that the "delay mode" feature is no longer required. So get rid of it.
