mac80211: VHT peer STA caps Save the AP's VHT capabilities (in managed mode) and make them available to the driver in the station information. Unlike HT capabilities, they aren't restricted to the common capabilities, so drivers must be aware of their own capabilities.

mac80211: stop toggling IEEE80211_HT_CAP_SUP_WIDTH_20_40 For VHT, many more bandwidth changes are possible. As a first step, stop toggling the IEEE80211_HT_CAP_SUP_WIDTH_20_40 flag in the HT capabilities and instead introduce a bandwidth field indicating the currently usable bandwidth to transmit to the station. Of course, make all drivers use it. To achieve this, make ieee80211_ht_cap_ie_to_sta_ht_cap() get the station as an argument, rather than the new capabilities, so it can set up the new bandwidth field. If the station is a VHT station and VHT bandwidth is in use, also set the bandwidth accordingly. Doing this allows us to get rid of the supports_40mhz flag as the HT capabilities now reflect the true capability instead of the current setting. While at it, also fix ieee80211_ht_cap_ie_to_sta_ht_cap() to not ignore HT cap overrides when MCS TX isn't supported (not that it really happens...)
