wifi: ath12k: Support Downlink Pager Stats
Add support to request downlink pager stats from firmware through HTT
stats type 36. These stats give paging information like number of pages,
their timestamp, number of locked and free pages, synchronous and
asynchronous locked pages.
Note: MCC firmware version -
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 responds to
the event requesting stats, but it does not give any data.
Sample output:
-------------
echo 36 > /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_DLPAGER_STATS_TLV:
ASYNC locked pages = 2
SYNC locked pages = 0
Total locked pages = 2
Total free pages = 127
LOCKED PAGES HISTORY
last_locked_page_idx = 0
Index - 0 ; Page Number - 8495 ; Num of pages - 1 ; Timestamp - 4031009360us
Index - 1 ; Page Number - 7219 ; Num of pages - 2 ; Timestamp - 885379515us
Index - 2 ; Page Number - 0 ; Num of pages - 0 ; Timestamp - 0us
Index - 3 ; Page Number - 0 ; Num of pages - 0 ; Timestamp - 0us
.....
UNLOCKED PAGES HISTORY
last_unlocked_page_idx = 0
Index - 0 ; Page Number - 7144 ; Num of pages - 2 ; Timestamp - 4032070008us
Index - 1 ; Page Number - 7214 ; Num of pages - 2 ; Timestamp - 885379512us
