nl80211/cfg80211: support VHT channel configuration
Change nl80211 to support specifying a VHT (or HT) using the control channel frequency (as before) and new attributes for the channel width and first and second center frequency. The old channel type is of course still supported for HT. Also change the cfg80211 channel definition struct to support these by adding the relevant fields to it (and removing the _type field.) This also adds new helper functions: - cfg80211_chandef_create to create a channel def struct given the control channel and channel type, - cfg80211_chandef_identical to check if two channel definitions are identical - cfg80211_chandef_compatible to check if the given channel definitions are compatible, and return the wider of the two This isn't entirely complete, but that doesn't matter until we have a driver using it. In particular, it's missing - regulatory checks on the usable bandwidth (if that even makes sense) - regulatory TX power (database can't deal with it) - a proper channel compatibility calculation for the new channel types Signed-off-by: Johannes Berg <johannes.berg@intel.com>
