From e2b2c390b018c3f0ab6bcf8f9ffbc94471d7bf6a Mon Sep 17 00:00:00 2001 From: Felix Fietkau <nbd@nbd.name> Date: Mon, 25 Jan 2021 22:24:31 +0100 Subject: [PATCH] mt76: mt7615: reduce VHT maximum MPDU length With a maximum length of 7991, the radio sometimes locks up under load when transmitting A-MSDU frames to lots of stations. Using the lower limit makes it work reliably again Signed-off-by: Felix Fietkau <nbd@nbd.name> --- drivers/net/wireless/mediatek/mt76/mt7615/init.c | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/net/wireless/mediatek/mt76/mt7615/init.c b/drivers/net/wireless/mediatek/mt76/mt7615/init.c index f345cb43cb016b..7c24daf2581f27 100644 --- a/drivers/net/wireless/mediatek/mt76/mt7615/init.c +++ b/drivers/net/wireless/mediatek/mt76/mt7615/init.c @@ -500,7 +500,6 @@ void mt7615_init_device(struct mt7615_dev *dev) dev->mphy.sband_2g.sband.ht_cap.cap |= IEEE80211_HT_CAP_LDPC_CODING; dev->mphy.sband_5g.sband.ht_cap.cap |= IEEE80211_HT_CAP_LDPC_CODING; dev->mphy.sband_5g.sband.vht_cap.cap |= - IEEE80211_VHT_CAP_MAX_MPDU_LENGTH_7991 | IEEE80211_VHT_CAP_MAX_A_MPDU_LENGTH_EXPONENT_MASK; mt7615_cap_dbdc_disable(dev); dev->phy.dfs_state = -1; -- GitLab
