From 5c0dc2fcfec606cf9f2d28ff31bbeb0a6225b27a Mon Sep 17 00:00:00 2001 From: Eyal Shapira Date: Thu, 2 Feb 2012 19:06:45 +0200 Subject: [PATCH] wl12xx: add forced_ps mode For certain WiFi certification tests forcing PS is necessary. Since DPS is now enabled in the FW and this can't be achieved by using netlatency this required a new config option.
