Hello, dvb frontend maintainer: I work at mediatek company. Currently I develop TV with Linux DVB system. I would like to implement the following LNB use cases: user space would like to know if frontend device node have LNB or not. I want to use "DTV_FE_CAPABILITY" to represent above LNB capability, but I am afraid that my usage is not suitable to the original definition. So I would like to consult the following quesitons: 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 Sorry to bother you and thanks for your helps. BRs, YP
