Subject: [PATCH 13/16] ratp: send initial data in behaviour B if any pending
Date: Thu, 15 Jun 2017 13:14:17 +0200	[thread overview]
Message-ID: <20170615111420.5318-14-aleksander@aleksander.es> (raw)
In-Reply-To: <20170615111420.5318-1-aleksander@aleksander.es>

And also, use ratp_send_ack() instead of manually constructing an ACK
if no data is pending to be sent.
