mac80211: minstrel: fix using short preamble CCK rates on HT clients
mi->supported[MINSTREL_CCK_GROUP] needs to be updated short preamble rates need to be marked as supported regardless of whether it's currently enabled. Its state can change at any time without a rate_update call. Fixes: 782dda00ab8e ("mac80211: minstrel_ht: move short preamble check out of get_rate") Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
