From 876d0e95bc99493dcb17737cf246fd7fc47a61b9 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Fri, 28 Dec 2018 11:00:47 +0100 Subject: [PATCH] mt76: mac: minor optimizations in mt76x02_mac_tx_rate_val Do not set bw variable to zero for legacy rates since it is already initialized to zero. Moreover set nss to 1 just for legacy rates since nss will be properly set for VHT/HT rates Signed-off-by: Lorenzo Bianconi --- mt76x02_mac.c | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/mt76x02_mac.c b/mt76x02_mac.c index f26c213c..6be1b137 100644 --- a/mt76x02_mac.c +++ b/mt76x02_mac.c @@ -130,10 +130,8 @@ static __le16 mt76x02_mac_tx_rate_val(struct mt76x02_dev *dev, const struct ieee80211_tx_rate *rate, u8 *nss_val) { + u8 phy, rate_idx, nss, bw = 0; u16 rateval; - u8 phy, rate_idx; - u8 nss = 1; - u8 bw = 0; if (rate->flags & IEEE80211_TX_RC_VHT_MCS) { rate_idx = rate->idx; @@ -164,7 +162,7 @@ mt76x02_mac_tx_rate_val(struct mt76x02_dev *dev, phy = val >> 8; rate_idx = val & 0xff; - bw = 0; + nss = 1; } rateval = FIELD_PREP(MT_RXWI_RATE_INDEX, rate_idx);
