Re: [lwip-users] how lwip know internet cable is unplug

[ake . forslund]

Thanks for the tip. set_link_up/down looks
pretty safe to use from my rx-thread (rx handled by a separate thread triggered
by eth-interrupt). Is it the callback that need to be protected from threding
issues?

Nearly: it should call netif_set_link_up/down (watch out for threading
issues!), which in turn calls user-specified callbacks. This has to be
enabled using a define (I think it's turned off by default).
