Subject: [PATCH 1/4] mac80211: minstrel_ht: fix per-group max throughput rate initialization
Date: Tue, 20 Aug 2019 11:54:46 +0200	[thread overview]
Message-ID: <20190820095449.45255-1-nbd@nbd.name> (raw)

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

Fixes: 5935839ad73583 ("mac80211: improve minstrel_ht rate sorting by throughput & probability")
