    Subject[PATCH AUTOSEL 4.14 273/371] mac80211: minstrel_ht: fix per-group max throughput rate initialization
    Date
    From: Felix Fietkau <nbd@nbd.name>

    [ Upstream commit 56dd918ff06e3ee24d8067e93ed12b2a39e71394 ]

    The group number needs to be multiplied by the number of rates per group
    to get the full rate index

    Fixes: 5935839ad735 ("mac80211: improve minstrel_ht rate sorting by throughput & probability")
