UPSTREAM: wifi: ath12k: Add support TX hardware queue stats
Add support to request and receive TX hardware queue stats using HTT stats type 3. This stats type reports MPDU mac id and hardware queue information, including xretry, BAR, RTS, CTS, self, and QoS-null counts, along with underrun, flush, and filter counters. Sample output: ------------- echo 3 >/sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats_type cat /sys/kernel/debug/ath12k/pci-0000\:58\:00.0/mac0/htt_stats HTT_TX_HWQ_STATS_CMN_TLV: mac_id = 0 hwq_id = 0 xretry = 0 underrun_cnt = 0 flush_cnt = 0 filt_cnt = 0 null_mpdu_bmap = 0 user_ack_failure = 379 ack_tlv_proc = 0 sched_id_proc = 0 null_mpdu_tx_count = 0 mpdu_bmap_not_recvd = 0 num_bar = 0 rts = 0 cts2self = 0 qos_null = 0 mpdu_tried_cnt = 379 mpdu_queued_cnt = 379 mpdu_ack_fail_cnt = 0 mpdu_filt_cnt = 0 false_mpdu_ack_count = 0 txq_timeout = 0 Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.5-01651-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3 Signed-off-by: Aaradhana Sahu <aaradhana.sahu@oss.qualcomm.com> Reviewed-by: Baochen Qiang <baochen.qiang@oss.qualcomm.com> Link: https://patch.msgid.link/20260123071253.2202644-4-aaradhana.sahu@oss.qualcomm.com Signed-off-by: Jeff Johnson <jeff.johnson@oss.qualcomm.com> Signed-off-by: Miaoqing Pan <miaoqing.pan@oss.qualcomm.com>
