[lwip-devel] [task #6930] Implement SO_LINGER

[Frédéric Bernon]

Follow-up Comment #10, task #6930 (project lwip):

If I resume your idea:

- netconn_close/do_close now just do a tcp_close for NETCONN_TCP, and return
ERR_VAL for the other (in this case, I think to return ERR_OK will be better
to simplify using, after all, at socket layer, we also "close" the socket -
even if in fact, we only delete it & its conn).

- Not sure: do you want or not to call netconn_close (and also
netconn_delete) in lwip_close (it's not in your patch)?
