These stats give AST entries related information such as software peer id, MAC address, pdev id, vdev, id, next hop, etc. Sample output: ------------- echo 41 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats HTT_AST_ENTRY_TLV: ast_index = 10 mac_addr = 00:00:00:01:00:00 sw_peer_id = 0 pdev_id = 3 vdev_id = 255 next_hop = 0 mcast = 0 monitor_direct = 0 mesh_sta = 0 mec = 0 intra_bss = 0 Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 Signed-off-by: Roopni Devanathan <quic_rdevanat@quicinc.com> --- .../wireless/ath/ath12k/debugfs_htt_stats.c | 56 +++++++++++++++++++ .../wireless/ath/ath12k/debugfs_htt_stats.h | 18 ++++++ drivers/net/wireless/ath/ath12k/dp.h | 12 ++++ 3 files changed, 86 insertions(+)
