From f056658bb9c3085d5ec52fbdd45b38d55b899cc9 Mon Sep 17 00:00:00 2001 From: "Zhu, Yi" Date: Fri, 5 Dec 2008 07:58:38 -0800 Subject: iwlwifi: fix time interval misuse in iwl_poll_{direct_}bit The patch fixes the misuse of microsecond with millisecond in the polling mechanism of the iwlwifi driver. The impact of this problem is the unacceptable latency for the whole system (especially during bringing down the wlan interface).
