CAPS field for passing required
   configuration information from FW to a VF (this field is to allow safely
                   adding new SRIOV capabilities which require support in VF drivers, too).
   Bits will set here by FW in response to PF-driver configuration commands which
   will activate as yet undefined new SRIOV features. The VF will test to see that
   all required capabilities indicated by this field are supported (i.e., if a bit
   is set and the VF driver does not recognize that bit, it must abort
   its initialization).  Currently, no bits are set.

4. Added a CLOSE_PORT wrapper.  The PF context needs to keep track of how many VF contexts
   have the port open.  The PF context will not actually issue the FW close port command
   until the last port user issues a CLOSE_PORT request.
