wifi: ath12k: Support Latency Stats
Add support to request latency stats from firmware through HTT stats
type 25. These stats give information about count of transmitted and
received MAC Protocol Data Units(PDU) and Service Data Units(SDU)
and other latency stats.
Sample output:
-------------
echo 25 > /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_STATS_LATENCY_CTX_TLV:
duration = 0
tx_msdu_cnt = 0
tx_mpdu_cnt = 0
rx_msdu_cnt = 0
rx_mpdu_cnt = 0
HTT_STATS_LATENCY_PROF_TLV:
Latency name = PROF_SCH_ENQ_TQM_CMDS
count = 0
minimum = 4294967295
maximum = 0
.....
HTT_STATS_LATENCY_CNT_TLV:
prof_enable_cnt = 39
