My approach is to send a signal to a separate task to handle the cable-plug/unplug events
Ake:
For your approach, who send a signal to the task ? the driver ? my driver can get the link status by polling, not interrupt, so it takes more cpu time..I stop
using it
And try to find another one to replace… maybe it need HW sensor support.

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.
