    IB/core: Support accessing SA in virtualized environment · a0c1b2a3
    Eli Cohen authored
    Per the ongoing standardisation process, when virtual HCAs are present
    in a network, traffic is routed based on a destination GID. In order to
    access the SA we use the well known SA GID.
    
    We also add a GRH required boolean field to the port attributes which is
    used to report to the verbs consumer whether this port is connected to a
    virtual network. We use this field to realize whether we need to create
    an address vector with GRH to access the subnet administrator. We clear
    the port attributes struct before calling the hardware driver to make
    sure the default remains that GRH is not required.
