For ath11k board files it's best to file a bug in bugzilla: https://wireless.docs.kernel.org/en/latest/en/users/drivers/ath11k/bugreport.html For ath11k discussions we have a mailing list, adding it now: https://wireless.docs.kernel.org/en/latest/en/users/drivers/ath11k/mailinglist.html -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
