From a8ae833657a45746debde85c38bb7f070d344026 Mon Sep 17 00:00:00 2001 From: Harshitha Prem Date: Mon, 17 Apr 2023 13:35:01 +0300 Subject: [PATCH] wifi: ath11k: Prevent REO cmd failures Prevent REO cmd failures causing double free by increasing REO cmd ring size and moving REO status ring mask to IRQ group 3 from group 0 to separate from tx completion ring on IRQ group 0 which may delay reo status processing.
