Subject: [PATCH AUTOSEL 4.14 273/371] mac80211: minstrel_ht: fix per-group max throughput rate initialization
Date: Thu, 16 Jan 2020 12:22:25 -0500 [thread overview]
Message-ID: <20200116172403.18149-216-sashal@kernel.org> (raw)
In-Reply-To: <20200116172403.18149-1-sashal@kernel.org>
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")
