The TCP driver should discard(ignore) the incoming TCP segment when there's no TCB found to handle it, because that TCP segment may be subjected to be received by other running Managed Network instance with it's own network stack to handle it. Force sending reset segment in this case would just discrupt any TCP connection except the one established by EFI TCP protocol, which is not make sense imho.
