Yeah, that's missing.

Not MCS bitmap, "vht_mcs_set" is relevant for VHT.
It seems to me that we'd need a new flag
HOSTAPD_MODE_FLAG_VHT_INFO_KNOWN that driver_nl80211 sets
unconditionally (see phy_info_band()/phy_info_vht_capa() there).
It seems I forgot to add a flag saying "VHT is supported", and never
even set vht_mcs_set to ff:ff:ff:ff:ff:ff:ff:ff, so maybe this is all
completely wrong now?
