From 9816f9812adb2cfa23b99f13d86750ab21a49647 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 28 Jul 2020 20:41:09 +0200 Subject: [PATCH] mt76: move mt76_check_agg_ssn to driver tx_prepare calls mt7615 and newer drivers do not need this, since they use sequence number offload Moving this code also reduces the number of callsites to make it easier to review Signed-off-by: Felix Fietkau --- mt76.h | 1 + mt7603/mac.c | 2 ++ mt76x02_mac.c | 2 ++ tx.c | 38 +++++++++++++------------------------- 4 files changed, 18 insertions(+), 25 deletions(-) diff --git a/mt76.h b/mt76.h index c7afc1c7..f11978f2 100644 --- a/mt76.h +++ b/mt76.h @@ -914,6 +914,7 @@ void mt76_txq_remove(struct mt76_dev *dev, struct ieee80211_txq *txq); void mt76_wake_tx_queue(struct ieee80211_hw *hw, struct ieee80211_txq *txq); void mt76_stop_tx_queues(struct mt76_dev *dev, struct ieee80211_sta *sta, bool send_bar); +void mt76_tx_check_agg_ssn(struct ieee80211_sta *sta, struct sk_buff *skb); void mt76_txq_schedule(struct mt76_phy *phy, enum mt76_txq_id qid); void mt76_txq_schedule_all(struct mt76_phy *phy); void mt76_tx_tasklet(unsigned long data); diff --git a/mt7603/mac.c b/mt7603/mac.c index 8060c151..625dc6d5 100644 --- a/mt7603/mac.c +++ b/mt7603/mac.c @@ -1036,6 +1036,8 @@ int mt7603_tx_prepare_skb(struct mt76_dev *mdev, void *txwi_ptr, IEEE80211_TX_CTL_CLEAR_PS_FILT)) || (info->control.flags & IEEE80211_TX_CTRL_PS_RESPONSE)) mt7603_wtbl_set_ps(dev, msta, false); + + mt76_tx_check_agg_ssn(sta, tx_info->skb); } pid = mt76_tx_status_skb_add(mdev, wcid, tx_info->skb); diff --git a/mt76x02_mac.c b/mt76x02_mac.c index e4e03bea..af2e6ffc 100644 --- a/mt76x02_mac.c +++ b/mt76x02_mac.c @@ -349,6 +349,8 @@ void mt76x02_mac_write_txwi(struct mt76x02_dev *dev, struct mt76x02_txwi *txwi, memset(txwi, 0, sizeof(*txwi)); + mt76_tx_check_agg_ssn(sta, skb); + if (!info->control.hw_key && wcid && wcid->hw_key_idx != 0xff && ieee80211_has_protected(hdr->frame_control)) { wcid = NULL; diff --git a/tx.c b/tx.c index 40ec55ac..d8252e28 100644 --- a/tx.c +++ b/tx.c @@ -83,17 +83,27 @@ mt76_txq_get_qid(struct ieee80211_txq *txq) return txq->ac; } -static void -mt76_check_agg_ssn(struct mt76_txq *mtxq, struct sk_buff *skb) +void +mt76_tx_check_agg_ssn(struct ieee80211_sta *sta, struct sk_buff *skb) { struct ieee80211_hdr *hdr = (struct ieee80211_hdr *)skb->data; + struct ieee80211_txq *txq; + struct mt76_txq *mtxq; + u8 tid; - if (!ieee80211_is_data_qos(hdr->frame_control) || + if (!sta || !ieee80211_is_data_qos(hdr->frame_control) || !ieee80211_is_data_present(hdr->frame_control)) return; + tid = skb->priority & IEEE80211_QOS_CTL_TAG1D_MASK; + txq = sta->txq[tid]; + mtxq = (struct mt76_txq *)txq->drv_priv; + if (!mtxq->aggr) + return; + mtxq->agg_ssn = le16_to_cpu(hdr->seq_ctrl) + 0x10; } +EXPORT_SYMBOL_GPL(mt76_tx_check_agg_ssn); void mt76_tx_status_lock(struct mt76_dev *dev, struct sk_buff_head *list) @@ -288,19 +298,6 @@ mt76_tx(struct mt76_phy *phy, struct ieee80211_sta *sta, ieee80211_get_tx_rates(info->control.vif, sta, skb, info->control.rates, 1); - if (sta && ieee80211_is_data_qos(hdr->frame_control)) { - struct ieee80211_txq *txq; - struct mt76_txq *mtxq; - u8 tid; - - tid = skb->priority & IEEE80211_QOS_CTL_TID_MASK; - txq = sta->txq[tid]; - mtxq = (struct mt76_txq *)txq->drv_priv; - - if (mtxq->aggr) - mt76_check_agg_ssn(mtxq, skb); - } - if (ext_phy) info->hw_queue |= MT_TX_HW_QUEUE_EXT_PHY; @@ -390,9 +387,6 @@ mt76_release_buffered_frames(struct ieee80211_hw *hw, struct ieee80211_sta *sta, if (!skb) break; - if (mtxq->aggr) - mt76_check_agg_ssn(mtxq, skb); - nframes--; if (last_skb) mt76_queue_ps_skb(dev, sta, last_skb, false); @@ -446,9 +440,6 @@ mt76_txq_send_burst(struct mt76_phy *phy, struct mt76_sw_queue *sq, ampdu = IEEE80211_SKB_CB(skb)->flags & IEEE80211_TX_CTL_AMPDU; limit = ampdu ? 16 : 3; - if (ampdu) - mt76_check_agg_ssn(mtxq, skb); - idx = dev->queue_ops->tx_queue_skb(dev, qid, skb, wcid, txq->sta); if (idx < 0) @@ -479,9 +470,6 @@ mt76_txq_send_burst(struct mt76_phy *phy, struct mt76_sw_queue *sq, info->control.rates[0] = tx_rate; - if (cur_ampdu) - mt76_check_agg_ssn(mtxq, skb); - idx = dev->queue_ops->tx_queue_skb(dev, qid, skb, wcid, txq->sta); if (idx < 0)
