Follow-up Comment #9, bug #55380 (project lwip):
I wanted to check out the code changes, now that this bug has been marked as
fixed, in order to patch my sources, but I could not find it below. Have you
not pushed it yet?

For other readers, the reason why this issue does need to be fixed is that
dhcp_release_and_stop() unconditionally clears the interface's IP address,
even if the address was not set by DHCP.
This breaks applications that want to use a fallback IP address if DHCP fails,
but my still want to stop and restart DHCP in case a DHCP server does show up
later on.
