Dunno. bcm43xx has this feature too, it even allows you to bypass the second CRC check in the PLCP header. Picks up your microwave with that ;) Maybe take this into account for the driver API when implementing IFF_PROMISC as we talked about? > Daniel, does zd1211 send information about failed CRC check with the > packet?

Hence, we'd have to recheck the CRC(s). johannes
