No, that makes no sense. 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.
