Hi Sven,

adding ath10k@lists.infradead.org.

Yeah, it would be great to get proper ath10k support to OpenWrt. Thanks
for working on this!

Where did you take the ath10k patches? ath10k is under heavy
development, so I strongly recommend taking patches directly from
ath-next branch of my ath.git. That way you would be using the latest
and greatest.

Could you report the I9300 issue to the ath10k list with more details,
please? We can try to investigate it.

That was with 10.1 firmware? AFAIK it doesn't support adhoc at all. I
think we need to add a firmware feature flag to disable adhoc with that
firmware.

Yeah, this is annoying. But firmware doesn't report this to the host at
all so there is not much ath10k can do right now. But I'll send a query
to the firmware team if they could provide that information to ath10k.

On some QCA988x boards cold reset seems to cause problems on the PCI
bus. We are investigating this.

This is new to me. Can you report this to the ath10k list, please?

What firmware version was this? The version printed here seems to be
corrupted.
