๐ Members ๐
channelsโ array of channels the hardware can operate with in this band. ๐กbitratesโ array of bitrates the hardware can operate with in this band. Must be sorted to give a valid"supported rates"IE, i.e. CCK rates first, then OFDM. ๐ฅbandโ the band this structure represents. ๐n_channelsโ number of channels inchannels. ๐n_bitratesโ number of bitrates inbitrates. โจht_capโ HT capabilities in this band. ๐ฆvht_capโ VHT capabilities in this band. ๐ธs1g_capโ S1G capabilities in this band (S1G band only, of course). ๐edmg_capโ EDMG capabilities in this band. ๐n_iftype_dataโ number of iftype data entries. ๐ซถiftype_dataโ interface type data entries. Note that the bits intypes_maskinside this structure cannot overlap (i.e. only one occurrence of each type is allowed across all instances ofiftype_data). โ ๏ธ
