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?

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
