    mac80211: minstrel_ht: Increase the range of handled rate indexes · d4d141ca
    Karl Beldan authored
    Since 5935839a
     ("mac80211: improve minstrel_ht rate sorting by
    throughput & probability"), the rate indexes are manipulated via u8's
    and hence allow for a maximum of 256 mcs_group entries in
    ATM, minstrel_ht advertizes support up to 3HTSS@40MHz, consuming:
    8(MCS_GROUP_RATES) * (3(SS)*2(GI)*2(BW)+1(CCK)), i.e. 104 entries.
    Support for 3VHTSS@80MHz will require:
    10(MCS_GROUP_RATES) * (3(SS)*2(GI)*2(BW)+1(CCK)) +
    10(MCS_GROUP_RATES) * (3(SS)*2(GI)*3(BW)), i.e. 130 + 180 entries.
    This change moves from u8s to u16s where necessary.
