Hi lwIP,
According to a message from a long time ago [1], there's no way to
perform a graceful shutdown of an lwIP instance. Is that still true?
Yes, that's still true.
However, by now I have changed my mind. There are more and more people
using lwIP outside its original target - small microcontrollers. In
small microcontrollers, it made sense to not support shutdown. However,
I think by now it might be worth a try to implement such a shutdown, as
long as it doesn't grow size for small microcontroller usage.

For context, I'm currently working with an executable that, on startup,
calls lwip_init(), netif_set_up(), netif_set_link_up(),
netif_set_default(), tcp_bind_to_netif(), tcp_bind_netif(),
tcp_listen(), and tcp_accept(). On completion, the process terminates
without unwinding any of these steps. I'm trying to convert this
executable into a library that could be started, stopped, and started again.
Is there a recommended pattern for stopping and restarting lwIP?
Thanks,
Ben Schwartz
