When the channel gets disconnected, you will get an upstream event (a
ChannelStateEvent) informing you about the disconnection.

When you disconnect the channel yourself (by calling
Channels.close()), you will generate a downstream event, which will
disconnect the socket.  Once the socket gets disconnected, you'll get
an upstream event (the same as you'd get in the previous case).

That's how you can distinguish between the two.
