[linux-dvb] [PATCH] SS2 : Fix for OpenWholeBandWidth

[Vincenzo Di Massa <hawk78_it@yahoo.it>]

This patch let SS2 recieve the whole ts stream.
To use it select pid 8192.
To use it with szap you have to commnet the istructions that check for
valid pids (8192 sems to be too high!).

I don't know if pids need to be removed before disabling the pid filter.
For now I'll leave them alone, this works for me.

It seems that there are 2 pid filters. One is the hawrdware filter, the
other is a software filter. Are both needed?
