There seems to be a way to retrieve this info directly per tx completion:
https://git.codelinaro.org/clo/qsdk/oss/system/feeds/wlan-open/-/raw/win.wlan_host_opensource.4.0.r39/patches/ath11k/0149-ath11k-fix-tx-bitrate-retry-signal-in-station-dump.patch
and the try_cnt comes from
https://git.codelinaro.org/clo/qsdk/oss/system/feeds/wlan-open/-/raw/win.wlan_host_opensource.4.0.r39/patches/ath11k/0117-001-ath11k-optimize-tx-completions.patch
