Add support to record the number of frames enqueued, hardware descriptor type, encapsulation/encryption types used, frames dropped and completed. This is useful for understanding the datapath performance and tune the peak throughput. The link specific stats can be viewed through the below debugfs file cat /sys/kernel/debug/ieee80211/phy0/netdev:wlan1/link_stats link[0] Tx Unicast Frames Enqueued = 9 link[0] Tx Broadcast Frames Enqueued = 78689 link[0] Tx Frames Completed = 78698 link[0] Tx Frames Dropped = 0 link[0] Tx Frame descriptor Encap Type = raw:0 native wifi:78698 ethernet:0 link[0] Tx Frame descriptor Encrypt Type = 0:78698 1:0 2:0 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:0 11:0 link[0] Tx Frame descriptor Type = buffer:78698 extension:0 ------------------------------------------------------ link[1] Tx Unicast Frames Enqueued = 0 link[1] Tx Broadcast Frames Enqueued = 78689 link[1] Tx Frames Completed = 78689 link[1] Tx Frames Dropped = 0 link[1] Tx Frame descriptor Encap Type = raw:0 native wifi:78689 ethernet:0 link[1] Tx Frame descriptor Encrypt Type = 0:78689 1:0 2:0 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:0 11:0 link[1] Tx Frame descriptor Type = buffer:78689 extension:0 ------------------------------------------------------ Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Balamurugan Mahalingam <quic_bmahalin@quicinc.com> Link: https://patch.msgid.link/20250409155125.299380-1-quic_bmahalin@quicinc.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com>
