Jack Morgenstein 0a9a01884d mlx4: MAD_IFC paravirtualization ... The MAD_IFC firmware command fulfills two functions. First, it is used in the QP0/QP1 MAD-handling flow to obtain information from the FW (for answering queries), and for setting variables in the HCA (MAD SET packets). For this, MAD_IFC should provide the FW (physical) view of the data. This is the view that OpenSM needs. We call this the "network view". In the second case, MAD_IFC is used by various verbs to obtain data regarding the local HCA (e.g., ib_query_device()). We call this the "host view". This data needs to be paravirtualized. MAD_IFC therefore needs a wrapper function, and also needs another flag indicating whether it should provide the network view (when it is called by ib_process_mad in special-qp packet handling), or the host view (when it is called while implementing a verb). There are currently 2 flag parameters in mlx4_MAD_IFC already: ignore_bkey and ignore_mkey. These two parameters are replaced by a single "mad_ifc_flags" parameter, with different bits set for each flag. A third flag is added: "network-view/host-view".
