Currently I develop TV with Linux DVB system. I would like to ask the following questions about "DTV_FE_CAPABILITY" in Frontend.h: 1. The use case for DTV_FE_CAPABILITY in DVB property command. 2. Does it have any restriction for using this command? 3. What’s your suggestion for using this command? File path: include/uapi/linux/dvb/Frontend.h #define DTV_FE_CAPABILITY 16 Thanks for your help.
