To: Johannes Berg; +Cc: linux-wireless, ath11k, Miles Hu, John Crispin
From: Miles Hu <milehu@codeaurora.org>
This patch adds ath11k support for setting fixed HE rate/gi/ltf values that
we are now able to send to the kernel using nl80211. The added code is
reusing parts of the existing code path already used for HT/VHT. The new
helpers are symmetric to how we do it for HT/VHT.

Hi Kalle and John,
This patch includes auto-rate support as well which is part of the CAF
changes John mentioned in v55 change-log.
Auto-rate part was added by me into CAF.
Please add my sign-off on this patch.
Or let me know if you decide to remove that particular portion, then I
will send a separate patch.
Thanks.
