There is a chance that the random data sent via `ASP[idx_a]` would reach osmo-stp earlier than the `ASPUP_ACK` we sent for `ASP[idx_b]` -- this is what I was seeing when running `TC_m3ua_tcp_cli_srv`. In this test scenario only `ASP[idx_b]` is using TCP, and there is some delay likely caused by Nagle's algorithm.

Nagle should IMHO "obviously" be disabled for M3UA over TCP. IF it is enabled, that's a bug. We're not talking about an interactive telnet session here, where we need to wait for more characters.
