I need to trace back through the code to see where this is used, but I thought
the check was determining if an address conveyed using sockaddr_ib applied to
the port. Sockaddr_ib was intended to target IB-classic specifically. It
should apply to RoCE/IBoE as well. I don't think it applies to RoCEv2/IBoUDP
without a translation.
