[lwip-users] lwip netconn with ethernet disconnect

[jim]

Hi,

I have the lwip system working and it is awesome!

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.
Jim
