The commit "ath9k_hw: Fix exceed transmission burst-time of 5GHz" added a padding of 60 delimiters on the first subframe to work around an issue on AR9380, but it lacked the checks to prevent it from being applied to pre-AR9380, enterprise AR9380 or AR9580+ Signed-off-by: Felix Fietkau <redacted> Cc: Rajkumar Manoharan <redacted> --- drivers/net/wireless/ath/ath9k/reg.h | 1 + drivers/net/wireless/ath/ath9k/xmit.c | 4 +++- 2 files changed, 4 insertions(+), 1 deletions(-)diff --git a/drivers/net/wireless/ath/ath9k/reg.h b/drivers/net/wireless/ath/ath9k/reg.h index a3b8bbc..989514a 100644 --- a/drivers/net/wireless/ath/ath9k/reg.h +++ b/drivers/net/wireless/ath/ath9k/reg.h@@ -1131,6 +1131,7 @@ enum { #define AR_INTR_PRIO_ASYNC_ENABLE (AR_SREV_9340(ah) ? 0x4094 : 0x40d4) #define AR_ENT_OTP 0x40d8 #define AR_ENT_OTP_CHAIN2_DISABLE 0x00020000 +#define AR_ENT_OTP_MIN_PKT_SIZE_DISABLE 0x00800000 #define AR_ENT_OTP_MPSD 0x00800000
Looks like AR_ENT_OTP_MPSD was defined for this purpose, unfortunately it so difficult to understand anything from this macro. Can you also this redundant definition? Vasanth
