As I said it cannot be changed during runtime as "transceiver is being in receive mode" but there is the possibility to stop/start the hardware _transparent_ from the user to change the "filtering level". I say filtering level because I think this is what the standard uses as a term. The one which is needed here is promiscuous mode, otherwise yea we usually use the highest filtering level. When changing the "filtering level" it depends on interface type what we need to filter in softmac then and what's not. One thing in promiscuous mode and everything else than monitor is to check on if the checksum is valid and drop if necessary, same for address filtering, etc. I don't assume that the software filtering is 100% correct, but we should have a basis to adding more filters if necessary and we found something is missing? What do you think? - Alex
