The number of application tasks communicating with the tcpip_thread + the 
number of input packets queued for receiving.

That depends on your application: the number of RX packets (or segments for 
tcp) queued for a single raw/udp/tcp netconn/socket.

That depends on your application, too: the number accepted connections queued 
for a single listening netconn/socket. This somewhat interferes with the listen 
backlog and should probably be >= backlog.
