2 * dvbapi-support for Matrix Cam Air
3 *
4 * The code is based partially on module-dvbapi-azbox.
5 * the (closed source) oscam that comes with the MCA is
6 * apparently based on svn-revision 5124-5242.
7 * DEMUXMATRIX is essentially the old DEMUXTYPE which
8 * has changed since then.
9 *
10 * We may be able to implement add/remove-filter
11 * by adding/removing them from DEMUXMATRIX
12 * and reexecute mca_write_flt
13 * In some cases the MCA will send ECMs for multiple PIDS
14 * So it is apparently able to handle multiple filters
15 *
