Kieran,

You are right. I haven't notice that this part of the code wasn't part of lwip 
delevery. I will ask support to Analog Device

Christophe

That code is part of the Analog Devices port of lwIP, rather than lwIP itself.  
I doubt you'll get much support from Analog Devices, but it might be worth a 
try asking them.

If I were trying to debug this myself I'd investigate where the 
ADI_ETHER_BUFFERs get allocated and freed, and see if there was a possible leak 
of the buffers when the cable is unplugged.  Perhaps the driver is dropping the 
packets but not returning the buffers when there is no link?  Perhaps they are 
all sitting in a queue somewhere waiting to be sent?  Unfortunately as I don't 
have a copy of the Analog Devices port I can't answer these questions myself, 
but it might help you investigate your problem.

Kieran
