Fix sending rx_buf_sz to ath11k_dp_tx_htt_rx_filter_setup() to enable pktlog full or lite mode. Depending on mode update the trace buffer with log type full/lite. Pktlog lite is a lighter version of pktlog. This can be used to capture PPDU stats. These are useful for firmware performance debugging. pktlog lite dumps are enabled using, echo "0x0 1" > ath11k/IPQ8074 hw2.0/mac0/pktlog_filter Tested On: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01233-QCAHKSWPL_SILICONZ-1 v2 Signed-off-by: Anilkumar Kolli <akolli@codeaurora.org> Signed-off-by: Jouni Malinen <jouni@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20210721212029.142388-1-jouni@codeaurora.org
