According to the best of my knowledge, even in case of missing Acks,
backoff window gets increased.

yup, block-ack window limit appears to be the main culprit behind your
reduced
ampdu lengths. Check ath_tx_form_aggr, there is an if-condition specifically
checking whether your are exceeding block-ack window or not. If your sending
rate is quite high then increased lossess might trigger this c
Check the struct ath_txq. It's defined in ath9k.h. You might find it helpful

We tried changing backoff value range through this function in mac.c
REG_WRITE(ah, AR_DLCL_IFS(q),
SM(cwMin, AR_D_LCL_IFS_CWMIN) |
SM(qi->tqi_cwmax, AR_D_LCL_IFS_CWMAX) |
SM(qi->tqi_aifs, AR_D_LCL_IFS_AIFS));
Setting using 1,1 in place of cwMin and qi->tqi_cwmax respectively is giving
almost the
11 matches
