firesat: update isochronous interface, add CI support
I have finally managed to get the CI support for the card working. The
implementation is a bare minimum to get encrypted channels to work in
kaffeine. It works fine with my T/CI card. Now and then I get an AVC
timeout and have to retune a channel in order to get it to work. Once
the CAM seemed to hang so I needed to remove and insert it again. I.e.
there are a number of glitches.
The latest version contains the following changes:
- Implemented the new hpsb iso interface so that data can be received
from the card
- Reduced some timers for demux setup which caused scanning to timeout
- Added possibility to unload driver
- Added support for getting C/N ratio
- Added two debug parameters to the driver; ca_debug and
avc_comm_debug.
- Added CI support that works for me in kaffeine
- Started working on CI MMI support. It now supports:
o Enter menu
o Receiving MMI objects
- Added support for 64-bit platforms
- Corrected DVB-C modulations problems
