According to the FSF, it's not compatible with the GPLv2 [1], only
GPLv3. That is why mbed TLS is dual licensed with GPLv2:
https://tls.mbed.org/how-to-get

Some care would be needed in how it is incorporated into lwIP, or
perhaps, incorporating would be the wrong approach and it should just be
a case of the user linking against an mbed TLS they've built themselves.
