ath10k does not honour it.

As far as I understand you want to alter number of retries with regard
to RTS/CTS being used or not. If so I'm not aware of any mechanism to
tell that to firmware (this is rate-control related and rate-control
is offloaded by firmware entirely).

To my knowledge what you can do is change number of software retries
for aggregated and non-aggregated traffic via NON_AGG_SW_RETRY_TH and
AGG_SW_RETRY_TH WMI's pdev parameters. Perhaps you'll find this
