Subject: [PATCH 04/30] libfc: Do not login if the port is already started
Date: Fri, 26 Aug 2016 14:01:27 +0200 [thread overview]
Message-ID: <1472212913-39810-5-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1472212913-39810-1-git-send-email-hare@suse.de>
When the port is already started we don't need to login; that
will only confuse the state machine.
