IB/rdmavt: Add support for query_port, modify_port and get_port_immutable
rvt_query_port calls into the driver through a call back function query_port_state to populate the rest of ib_port_attr elements. rvt_modify_port calls into the driver if needed through a call back function shut_down_port() Signed-off-by: Harish Chegondi <harish.chegondi@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
