RTL-SDR: E4000 IF bandwidth

Hi!

I've just noticed one issue about E4000 driver that bothers me - IF
bandwidth at the chip is set to 8 MHz, where maximum bandwidth of
RTL2832U sampling is 3.2 MHz.

Wouldn't reducing IF bandwidth at tuner chip improve overall
sensitivity (and maybe noise level)?

best regards
