Subject: [PATCH 1/2] wifi: mt76: add tx_nss histogram to ethtool stats
Date:   Wed, 17 May 2023 11:22:58 +0800
Message-ID: <78ae2336a119f416eb970ee403f85db35af2ef09.1684280458.git.ryder.lee@mediatek.com>

Precedence: bulk

mt76_connac2_mac_fill_txs() counts tx_nss but ethtool doesn't show
stats. Add missing histogram accordingly.
