From 30abb330764366223f56f8c90e0b9ac3afd974a6 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Wed, 4 Mar 2015 15:43:44 +0200 Subject: [PATCH] ath10k: increase copy engine entries for rx wmi Having lower number of copy engine entries for target to host WMI ring is causing drops in receiving management frames. This issue is observed during max clients (128 clients) stress testing. While bursting deauthentication frames from simulated clients, approx. 70% of frames are getting dropped due to lower ring entries.
