The MAD_IFC firmware command fulfills two functions.
In the first case, 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).
In this function, MAD_IFC should provide the FW (physical) view
of the data. This is the view that OpenSM needs for its functioning.
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 thus 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".
