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