Details:

As mentioned on the mailing list
<http://lists.nongnu.org/archive/html/lwip-users/2018-11/msg00070.html>, lwIP
should inform the application about a successful DHCP reboot even if the
assigned address did not change. Currently, there does not appear to be a
consistent way to get a notification when the link becomes ready for TCP or
UDP, i.e. when a valid IP configuration was (re-)acquired. This would be
useful if the application needs to use TCP/UDP as sson as possible, including
after a reconnect. Therefore, some kind of callback for "IP ready" would be
useful.
