IB/rdmavt, hfi1, qib: Modify check_ah() to account for extended LIDs
rvt_check_ah() delegates lid verification to underlying driver. Underlying driver uses different conditions to check for dlid depending on whether the device supports extended LIDs Reviewed-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Dasaratharaman Chandramouli <dasaratharaman.chandramouli@intel.com> Signed-off-by: Don Hiatt <don.hiatt@intel.com> Signed-off-by: Dennis Dalessandro <dennis.dalessandro@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
