 I've also played around to get all packets received by the card with a 
given PID but that was a long time ago (as fas as I can remember the
driver version was at 0.6;  and lately I had no time to follow
changes in the driver :((( so there could be an easier way than the one
I describe here).
 What I've learned is the "all 0s mask" filters won't work (at least
didn't work for me)... this is a driver issue (or may be a hardware
limit) so even if you successfully patch the dvbd it is possible that it
won't work this way. I've managed to receive all packets (with a given
PID) by setting up two bit filters: one with data: $80, mask: $80 , the
other one with data: $00, mask: $80 (both filters mask by the first bit of
the packet: one of them filters out packets with first bit 0, the other
one is with first bit 1.. so you can receive all packets with two filters
:))
 I don't know how to implement it in dvbd.c , I've never saw that stuff,
cause I only use my card to watch TV (and no network reasons).
 Bye,
 David
