Subject: [PATCH v4 13/19] NTB: Rate limit ntb_qp_link_work
Date: Wed, 10 Jun 2015 05:08:18 -0400	[thread overview]
Message-ID: <26ce1a85c6ee91592fc6fcaa2bc407a26d04acbf.1433925092.git.Allen.Hubbe@emc.com> (raw)
In-Reply-To: <cover.1433925092.git.Allen.Hubbe@emc.com>
In-Reply-To: <cover.1433925092.git.Allen.Hubbe@emc.com>

When the ntb transport is connecting and waiting for the peer, the debug
console receives lots of debug level messages about the remote qp link
status being down.  Rate limit those messages.
