We got report that WCN7850 is not working with IWD [1][2]. Debug shows the reason is that IWD installs group key before pairwise key, which goes against WCN7850's firmware.
Reorder key install to workaround this.

Thanks for fixing this, Baochen.
I noticed the patches weren't clearly marked as fixes. Do you think we should ask the stable team to backport these once they are in mainline (e.g. after 6.17-rc1 is out)? Or do you think they are too intrusive and risky to backport or similar?
Yeah, I think they should be backported.
[ Also please try to remember to CC any (public) reporters. I only found out today that this had been addressed in linux-next. ]
Thanks, will keep in mind.
+Stable team, Per the above discussion please backport the series: https://msgid.link/20250523-ath12k-unicast-key-first-v1-0-f53c3880e6d8@quici...
This is a 0-day issue so ideally this should be backported from 6.6+

These are currently only in linux-next but would need to be in Linus's tree before they can be backported, so we'll need to send another requested once they are in mainline.
This is a 0-day issue so ideally this should be backported from 6.6+
By "0-day" you mean it has been there since the driver was added, right (and not that it's exploitable or similar)?

This is not the correct way to submit patches for inclusion in the stable kernel tree. Please read: https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html for how to do this properly.
