From cbd1ea87a198669537591cef9ee834d6986c169b Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Fri, 7 May 2010 11:39:02 +0300 Subject: [PATCH] wl1271: Reduce PSM entry hang over period from 128 => 1 ms Currently, we configure a 128ms hang over period for the PSM entry (the firmware will remain active for 128ms after sending the null func for PSM and getting an ack for it.) This is a huge power consumption issue, and appears unnecessary. So, configure the value to 1 ms.
