DMG operation is significantly different from non-DMG operation, even the A-MSDU format for example (an abbreviated format called "short A-MSDU" is used in DMG). Similarly beacons, etc., all kinds of operations are significantly different. Adding 60 GHz channels to hwsim would be essentially operating as non- DMG yet on a DMG channel, which makes no sense. I don't think anyone's planning to add DMG support to mac80211, and in the absence of a real driver requiring that it wouldn't make sense anyway. Quite possibly, it simply doesn't make sense period, because DMG operation is sufficiently different. johannes
