Hi,
i need to know the mac adress of a dvb frontend (pci number would also be helpfull).
I found no way to identify a dvb device by its frontend.
I looked at the dvb api code, and then i patched dvb_frontend.c, and frontend.h for my needs.
Below are the changes I made.
But the code don't works. I don't get the information I need.
My devices:
Philips TDA10046H DVB-T
Conexant CX24123/CX24109
Conexant CX24123/CX24109
Montage Technology DS3000/TS2020 -> works
The value dvbdev->adapter->proposed_mac seems to be empty, for some cards.
But on driver load I can see a mac address for every dvb device I have.
The mac address for these cards are outputted in function: void tveeprom_hauppauge_analog(...).
Maybe someone can help me.
Maybe there is another way of determining a dvb frontend by PCI Bus or something.
Identifying dvb devices can be very important on some situations.
