The dvb_net interface was meant for IP-via-DVB applications, where doing MPE (or ULE) processing in userspace would mean - copying packets to userspace for unpacking / processing - copying network packets back into kernel - so that other applications can copy them back from kernel via socket -> too much overhead For DVB-H it might be easier to just do it all in userspace, using the section filter API. Evaluating the data_broadcast_descriptor is the most complicated part of it ;-), the code for handling the sections can be copied from dvb-apps/test/test_dvr.c and dvb_net.c, plus you need to handle the IP+UDP headers (which I think isn't too complicated for broadcast data, but I have no clue about DVB-H ;-/). Another way would be to extend the NET_ADD_IF API to include MAC_address_range. However, I think the MAC from the MPE packet should always be copied completely, just the section filter mask (mask_normal etc. in dvb_net.c) should be changed.
