   4  * dvbapi-support for Matrix Cam Air
   5  *
   6  * The code is based partially on module-dvbapi-azbox.
   7  * the (closed source) oscam that comes with the MCA is
   8  * apparently based on svn-revision 5124-5242.
   9  * DEMUXMATRIX is essentially the old DEMUXTYPE which
  10  * has changed since then.
  11  *
  12  * We may be able to implement add/remove-filter
  13  * by adding/removing them from DEMUXMATRIX
  14  * and reexecute mca_write_flt
  15  * In some cases the MCA will send ECMs for multiple PIDS
  16  * So it is apparently able to handle multiple filters
  17  *
