Why not put this after the if (outbuf_len < sizeof(struct tls_record_layer)) check below?

Is this unrelated?

This too. More below.

Because you will potentially get it multiple times. If a read returns part of a record we might get to the the read() call for payload data down at line 1242 but not get the full record (so outbuf_len < record_len still). Then on the next kevent we would try to read more of the data, but on that next event we would get down to line 1235 again and print it out a second time.

Oh, yes. I used the medium tests locally when testing NIC TLS offload at Chelsio internally and we needed a case that was bigger than one MSS, but a smaller size was less overwhelming for debugging data. I'll drop all the medium tests from this.
