Subject: How to use "DTV_FE_CAPABILITY" command for Frontend.h of Linux DVB 

Hello STI maintainer,
	I work at mediatek company. 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.
BRs,
