Maybe we should change its name to better represent what the code does. before, maybe take a look on the IB spec... see the spec references mentioned by the patch to support IB_QPT_RAW_ETY which posted to the list in the past, but didn't make it to upstream yet @ http://lists.openfabrics.org/pipermail/general/2008-December/055954.html Also, IBA chapter 2, states that "Raw Datagram - A packet that contains an IBA Local Route Header, may contain an IBA Global Route Header, but does not contain an IBA Transport header, and is not handled by IBA transport services", && chapter 3, section 3.6.2 "IBA TRANSPORT SERVICES" explains everything in detail, including what is the difference between raw ethernet to raw ipv6, look for "The Raw Datagram service is not technically a transport but rather it is a data link service that allows a QP to send and receive raw datagram messages" and following text.
