Indroduce function lme2510_update_stats to update statistics directly from usb interrupt.Provide signal and snr wrap rounds for dvb v3 functions. Block and post bit are not available. When i2c_talk_onoff is on no statistics are available, with possible future hand over to the relevant frontend/tuner.
