wifi: ath12k: Support Pdev OBSS Stats
Browse files Browse the repository at this point in the history 
Add support to request pdev OBSS stats from firmware through stats
type 23. These stats give information about PPDUs transmitted or
tried to be transmitted in Spatial Reuse Groups(SRG), Parameterized
Spatial Reuse(PSR) and non-PSR groups.

Sample output:
-------------
echo 23 > /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_PDEV_OBSS_PD_STATS_TLV:
num_spatial_reuse_tx = 0
num_spatial_reuse_opportunities = 0
num_non_srg_opportunities = 0
num_non_srg_ppdu_tried = 0
.....

HTT_PDEV_OBSS_PD_PER_AC_STATS:
Access Category 0 (best effort)
num_non_srg_ppdu_tried = 0
num_non_srg_ppdu_success = 0
num_srg_ppdu_tried = 0
num_srg_ppdu_success = 0

Access Category 1 (background)
num_non_srg_ppdu_tried = 0
num_non_srg_ppdu_success = 0
num_srg_ppdu_tried = 0
num_srg_ppdu_success = 0
.....
