Follow-up Comment #1, bug #60607 (project lwip):

The code in question has been there since I started with lwIP some 15 years
ago. I don't know the exact reason for it, but I suppose one reason could be
to communicate with e.g. the ethernet netif's address from behind a PPP remote
host (depending on the routing).

However, I agree that in standard, routed netif setups, this should not really
be required.

We might want to disable this but add an option for users to enable if needed.
