Subject: [PATCH 07/12] wifi: mt76: mt7915: support enabling rx group-5 status
Date: Wed, 25 Oct 2023 12:03:49 -0700 [thread overview]
Message-ID: <20231025190351.2141832-7-greearb@candelatech.com> (raw)
In-Reply-To: <20231025190351.2141832-1-greearb@candelatech.com>
From: Ben Greear <greearb@candelatech.com>
When enabled, this allows per-skb rx rate reporting.
Enabling this may degrade RX performance, so it remains
disabled by default.
Signed-off-by: Ben Greear <greearb@candelatech.com>
