    IB/mlx4: Add support for IBoE · fa417f7b
    Eli Cohen authored
    Add support for IBoE to mlx4_ib.  The bulk of the code is handling the
    new address vector fields; mlx4 needs the MAC address of a remote node
    to include it in a WQE (for datagrams) or in the QP context (for
    connected QPs).  Address resolution is done by assuming all unicast
    GIDs are either link-local IPv6 addresses.
    
    Multicast group attach/detach needs to update the NIC's multicast
    filters; but since attaching a QP to a multicast group can be done
    before the QP is bound to a port, for IBoE we need to keep track of
    all multicast groups that a QP is attached too before it transitions
    from INIT to RTR (since it does not have a port in the INIT state).

      introduce too many bugs.  - Roland ]
