Jim, In my application each time I call LWIP I check the connection state reported by the PHY. I have a state machine that handles cable up/down. If it is down, when it comes back I re-init LWIP and anything that has been hanging on the line.
That works...every time...is there a better way?

I am wondering how to recover from cable disconnect in my application. On cable disconnect, the driver calls tcpip_callback_with_block which ends up successfully entering netif_set_link_down. My application is currently waiting on the receive mailbox through netconn_recv. What is the expected behavior when the cable is removed? I would have expected the blocking netconn_recv to return with an error. Thanks in advance for any help.
