If the problem is on ath10k side I would rather semove support for
802.11w altogether (until it's fixed). It's controlled with this flag:

	ieee80211_hw_set(ar->hw, MFP_CAPABLE);

Alternatively if it works on some hardware and not on others we could
make it per hw, for example disabled on QCA6174 and enabled on all

But I found some old documentation claiming that 802.11w can be disabled
from Network Manager, if it works that sounds like a good temporary

"pmf int32 0 Indicates whether Protected Management Frames (802.11w)
must be enabled for the connection."
