The semantic of promiscuous mode on the driver layer is to turn off
ack response, address filtering and crc checking. Some transceivers
don't allow a more fine tuning on what to enable/disable. I think we
should at least do the checksum checking per software then?

Sure there is a possible tune up for more "powerful" transceivers then...
