Subject: [PATCH 1/1] IB/ipoib: remove unnecessary port query
Date: Wed, 20 Aug 2014 11:15:08 -0400	[thread overview]
Message-ID: <20140820151508.14287.53954.stgit@phlsvlogin03.ph.intel.com> (raw)

There are two queries for port attributes going one
after another. A second call is not needed since port_attr
structure already holds the data.
