OK, so the ability to query the set of supported delivery systems
was missing from your proposal. But apps need it!
After sleeping it over, I think it would be
easier to understand and use to add a seperate ioctl:
// get bit set of supported delivery systems
#define FE_GET_DELSYS _IOR('o', 84, enum fe_delsys)
// get capabilites for one delivery system
#define FE_GET_CAPS _IOWR('o', 85, struct dvb_frontend_cap)
What do you think?
