[lwip-users] Syncronise netif_remove() with tcpip_thread

[Christoph Bartelmus]

Hi *.*,

I'm trying to port lwip to an embedded system. The net interface is  
running in its own thread. When I want to remove the interface, how can I  
make sure that tcpip_tread does not try to access the data structures just  
freed by netif_remove()?

I can reproduce a case where tcpip_thread tries sending a packet although  
the net interface has been just removed, causing havoc.

TIA,

Christoph
