Hi!
I think that is something you define in your ethernet driver. My approach is to send a signal to a separate task to handle the cable-plug/unplug events. In the task I currently
disable dhcp (if active) on cable-unplug signal and reenable it on cable-connect. it might be good to set an auto-ip when unplugged as well, but I'm not sure. Maybe it should be handled with the netif_set_up/down-functions instead, I'm still experimenting...

No, I'm not sure why you need any of your sockets to be non-blocking.
