Firmware that reports 0 and 7 only, as IPQ8074 and QCN9074 do, hides it. One patch per driver. --- Christopher Griffin (2): wifi: ath11k: don't bit-reverse the firmware's PPE thresholds wifi: ath12k: don't bit-reverse the firmware's PPE thresholds drivers/net/wireless/ath/ath11k/mac.c | 3 +-- drivers/net/wireless/ath/ath12k/mac.c | 3 +-- 2 files changed, 2 insertions(+), 4 deletions(-) --- base-commit: a3ddbb45768717b5c9f923489387cf55c838d1ad change-id: 20261104-ath-ppe-thresholds-bit-order-436ac99c5745 Best regards, -- Christopher Griffin
