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.
