Johannes Stezenbach 7635acd2d9 [PATCH] dvb: flexcop: fix USB transfer handling
- driver receives many null TS packets (pid=0x1fff).  They occupy the
  limited USB bandwidth and this leads to loss of video packets.  Enabling the
  null packet filter fixes this.

- packets that flexcop sends to USB have a 2 byte header that has to be
  removed.

- sometimes a TS packet is split between different urbs.  These parts have
  to be combined in a temporary buffer.
