This is more of an mbedtls related question. Honestly, without looking at the
code, I can't even tell you whether this is really a client certificate or the
certificate chain to trust for server certificates...

This is also mbedtls related. Lwip just passed the certificate through to
mbedtls code. I think I used openssl to create the certificates.
