Hello, I'm working on defining new channels for S1G PHYs in mac80211. These are in the 900MHz range and center frequency for the 1MHz channels are on a half MHz, while the existing channel definitions are in units of MHz. In order to support the new channels we could change the internal center frequency units to KHz and extend the nl80211 API so NL80211_FREQUENCY_ATTR_FREQ and NL80211_ATTR_WIPHY_FREQ get _KHZ variants while renaming the original attributes to _MHZ to reflect the units. >From looking at the code it looks like this should be fairly straightforward, if involving a lot of changes since the driver declarations would have to change too. Am I missing something obviously wrong, or does this sound reasonable? Thanks, Thomas
