-Some old versions of OpenSSL have a bug with memory BIOs, where DTLSv1_listen consumes the ClientHello out of the BIO,
-but then do_handshake expects the ClientHello to still be in there (but not the one that ships with Ubuntu 20.04). In
-particular, this is known to affect the OpenSSL v1.1.1 that ships with Ubuntu 18.04. To work around this, we used to deliver a
-second copy of the ClientHello after DTLSv1_listen has completed. This was safe to do unconditionally, because on newer
-versions of OpenSSL, the second ClientHello is treated as a duplicate packet, which is a normal thing that can happen
-over UDP. For more details, see:

-This was fixed in v1.1.1a, and all later versions. So now we should be able to delete this. The fix landed in
-OpenSSL master as 079ef6bd534d2, and then was backported to the 1.1.1 branch as d1bfd8076e28.
+Remove workaround for OpenSSL 1.1.1 DTLS ClientHello bug.
