Then there could be protocol-specific fields for each standard. I think that what you mean is, for the fields that WiMax and WiFi have in common, add a generic alias---e.g., IEEE80211_RADIOTAP_RATE = RADIOTAP_RATE, but do not assign new presence bits for common fields. That sounds ok to me. > I think the following would be globally useful: > > IEEE80211_RADIOTAP_TSFT > IEEE80211_RADIOTAP_RATE > IEEE80211_RADIOTAP_DB* > IEEE80211_RADIOTAP_ANTENNA All of those fields have specific definitions. Do they apply equally well to WiMax? > IEEE80211_RADIOTAP_FLAGS (though you might need a general flag set and a > protocol-specific flag set) Sure. The flags have almost run out, though. :-) Dave -- David Young OJC Technologies dyoung-eZodSLrBbDpBDgjK7y7TUQ@public.gmane.org Urbana, IL * (217) 278-3933 ext 24
