From 6c3872e1d52290dcd506473028867cacc6b7393d Mon Sep 17 00:00:00 2001 From: Trieu 'Andrew' Nguyen Date: Mon, 8 Feb 2010 13:53:05 -0800 Subject: [PATCH] iwlwifi: Adjusting PLCP error threshold for 1000 NIC While testing the station with the NIC 1000 family, it is found that the plcp error can easily exceed 50 value in 100mSecs. This creates unneccessary radio reset/tuning. This patch raises the PLCP error threshold of the NIC 1000 from 50 to 200 error count.
