Subject: [PATCH v2 16/16] ratp: user close may happen in SYN-RECEIVED state
Date: Wed, 21 Jun 2017 21:13:23 +0200	[thread overview]
Message-ID: <20170621191323.18191-17-aleksander@aleksander.es> (raw)
In-Reply-To: <20170621191323.18191-1-aleksander@aleksander.es>

The reference says:

     5.2.3. SYN-RECEIVED
     ...
     Departures
       - A CLOSE request is made by the user.  Create a packet with
         FIN set.  Send it and go to the FIN-WAIT state.

Add this missing step.

Probably not a real usecase for barebox anyway as there is no user
triggered close.
