@MichelRottleuthner approved this pull request.

Even with #13641 it doesn't seem possible to use the same procedure for testing as I described in #14034 because CoAp simply doesn't work for me with that. But that is probably related to #13641 itself.

Using `tests/lwip` I can confirm that using bare UDP and TCP with sock_async still works and this PR gives less dropped packets on fast incoming bursts. ACK.
