Who did the de-aggregation part, hardware or software? the de-aggregation for AMPDU the rx part is done in the hardware itself(with inputs from Vasanth). the rx buffer size of 3840 (msdu size) is allocated for each ath_buf during rx_init. please check for bf_mpdu in ath_rx_tasklet. > > Thanks for your time! > Mike -- thanks, shafi _______________________________________________ ath9k-devel mailing list ath9k-devel@lists.ath9k.org https://lists.ath9k.org/mailman/listinfo/ath9k-devel
