dvb-ttpci: Support full-ts hardware modification
Add support for the 'full-ts' hardware modification.
On full-featured cards the data throughput is limited by the hardware
design. The full-ts mod removes this bottleneck, i.e. the card is able
to deliver the complete transport stream of a transponder.
For details see http://www.escape-edv.de/endriss/dvb-full-ts-mod
Priority: normal
Signed-off-by: Oliver Endriss <[EMAIL PROTECTED]>
