From 0714890bf0fd23d847e2bb6aaf37ece050a18078 Mon Sep 17 00:00:00 2001 From: Felix Fietkau 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 --- mt7615/init.c | 1 - 1 file changed, 1 deletion(-) diff --git a/mt7615/init.c b/mt7615/init.c index 508a5095..40b1d14d 100644 --- a/mt7615/init.c +++ b/mt7615/init.c @@ -508,7 +508,6 @@ 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;
