Subject: [PATCHv7 6/9] ipoib: avoid ipoib over RoCEE
Date: Tue, 5 Jan 2010 12:33:15 +0200	[thread overview]
Message-ID: <20100105103315.GH31480@mtls03> (raw)

IPoIB is an implementation of IP over Infiniband transport. In the case of
RoCEE, the link layer is Ethernet so IP can work directly over Ethernet, so
disable IPoIB for none IB_LINK_LAYER_INFINIBAND ports.
