Now there are many nl80211_band such as NL80211_BAND_2GHZ/
NL80211_BAND_5GHZ/NL80211_BAND_6GHZ... In the same interface, if some bands
support EML, and other bands not support EML, then how to handler this
case?
Could move the "u16 eml_capabilities" into struct
ieee80211_sband_iftype_data
as well as "struct ieee80211_sta_eht_cap eht_cap"? Also same for "u16
mld_capa_and_ops".
