   4 Subject: [PATCH] wifi: ath11k: Prevent REO cmd failures
   5
   6 Prevent REO cmd failures causing double free by increasing REO cmd
   7 ring size and moving REO status ring mask to IRQ group 3 from group
   8 0 to separate from tx completion ring on IRQ group 0 which may delay
   9 reo status processing.
