Hm, yes there is most likely something wrong. But not sure whether this patch 
is actually the culprit. It looks to me like this would also be reported the 
same way without the patch. cec17c382140 ("ath10k: add per peer htt tx stats 
support for 10.4") seems to be your problem, right?

This patch only splits WMI_RATE_PREAMBLE_HT & WMI_RATE_PREAMBLE_VHT. And for 
WMI_RATE_PREAMBLE_HT (*not VHT*), it uses a slightly different approach. But 
the WMI_RATE_PREAMBLE_VHT part (which you see in your logs) is basically 
untouched.

Kind regards,
	Sven
