This lwIP configuration file has options that are common to all ports, and the ports are updated to use this file. This change is a no-op, the lwIP configuration remains the same for the four ports using this common file. This reduces code duplication, keeps the ports in sync, and makes it easier to update the configuration for all ports at once. Signed-off-by: Damien George <damien@micropython.org>
