iwi has never been a reliable packet sniffer but it sounds like a 
regression.  FWIW iwi sniffs by "scanning a channel" but since it wasn't 
possible to reliably abort a scan the scan requests were made for very 
short periods of time and then resubmitted on timeout.  This means you 
can easily miss frames between resubmitted scan requests.
