Subject: [RFC PATCH 09/11] IB/Verbs: Use management helper has_ipoib() and, cap_ipoib() for ipoib-check
Date: Fri, 27 Mar 2015 16:48:22 +0100 [thread overview]
Message-ID: <55157BC6.70400@profitbricks.com> (raw)
In-Reply-To: <551579CA.4030901@profitbricks.com>
Introduce helper has_ipoib() and cap_ipoib() to help us check if an
IB device or it's port support IP over Infiniband.
