There's some code in cfg80211.h that uses this value:
enum ieee80211_band {
IEEE80211_BAND_2GHZ = NL80211_BAND_2GHZ,
IEEE80211_BAND_5GHZ = NL80211_BAND_5GHZ,
/* keep last */
IEEE80211_NUM_BANDS
};
If the 60Ghz band goes here as well, IEEE80211_NUM_BANDS will be
incremented. I'm guessing this can be problematic for a lot of drivers
that use this value more or less blindly (and pass indices to FW etc).
At least the wlcore driver will be impacted.
So this probably should be added, but maybe keep IEEE80211_NUM_BANDS
the same for legacy reasons?
