ath12k - HTT timeout error with NCM86

[Dieter Knueppel]

Hi Jeff,

thanks a lot for your update on ath11/ath12 related vfio support.

That's actually bad news!

Do you know whether vfio support vanished per accident or intention?

I.e. I'm wondering on why the ath11 patch haven't made it into mainline?

Assume there are no other 802.11be Chipsets supported by Linux, which
can be used as AP within a VM?

Kind regards,

Dieter
