[PATCH RFCv9 1/4] dvb: Add DVBv5 stats properties for Quality of Service

2013-01-07 Thread Mauro Carvalho Chehab
The DVBv3 quality parameters are limited on several ways: - Doesn't provide any way to indicate the used measure, so userspace need to guess how to calculate the measure; - Only a limited set of stats are supported; - Can't be called in a way to require them to
