Subject: [PATCH 11/16] ratp: consolidate ratp_sn_expected() and ratp_an_expected()
Date: Thu, 15 Jun 2017 13:14:15 +0200	[thread overview]
Message-ID: <20170615111420.5318-12-aleksander@aleksander.es> (raw)
In-Reply-To: <20170615111420.5318-1-aleksander@aleksander.es>

This is no code change in ratp_sn_expected(), it's just rewritten in
the same way as ratp_an_expected(), which follows the RFC916 approach.
