Our implementation calls tcp_accepted() in the accept callback (remember it's 
the listener
not the new pcb) as per lwIP documentation. It updates the pending connection 
count on the listener.
If you don't call it, the pending connection count will eventually exceed the 
backlog value and the
listener will start dropping connections.
