Input docsis

Input docsis will read DOCSIS packets from a DVB-C or a ATSC/QAM card.
It it optimised for DOCSIS packets in several ways :

It will read only MPEG packets with the DOCSIS PID from the DVB card using hardware filtering
DOCSIS packets will be reassembled on the input level, making it faster for the core to process them
Both DVB-C and ATSC/QAM cards are supported and the correct DOCSIS version will be used accordingly
Less configuration parameters are required since DOCSIS have mandatory symbol rate
