[Giuseppe Modugno]

Follow-up Comment #5, patch #9823 (project lwip):

be made by the altcp_mbedtls_lower_poll() function. This allow reuse existing
cyclic TCP timer. And ensure your new function isn't called too much.

As Simon already observed, poll mechanism call rate will be too slow.

implementation can stop at some point).

I couldn't get your point. If ECP calculus are made in HW, I think they would
be much more fast and restartable wouldn't be useful.
