In order to decrease the delay ASIC_DELAY I did some testing and found
out that the absolute minimum with my card is 18ms. With 17ms there are
many dst_error_recovery messages in the log but the card does tune after
calling dst_error_recovery a couple of times. With any value lower the
card almost never tunes.
I think 20ms should be a safe value for this card.
