There is already a patch from Remi pending for this, see: https://msgid.link/cover.1732293922.git.r...@triplefau.lt Please see if that series addresses your needs. First Kalle, and then I, held this back due to lack of internal validation across supported platforms, but it is actually still on my TODO list: https://patchwork.kernel.org/project/linux-wireless/list/?series=911851 Let me make one more validation request internally since I know there is at least one ath10k-based project with active development. /jeff
