Thanks Ian for the comments and suggestions, which is input for further
work. Hope to start this poco a poco soon.

Probably it will require a bit of testing, it might be that some
fine-tuning is needed since a lower RTT also means a lower maximum
throughput -- but maybe that limit is fully sufficient for the target
operational range of CCID-3 (streaming, not bulk data transfer).
