From 43b5ffe1162a7fbaa89f1c392a28ac54c2e932f7 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Thu, 3 Dec 2009 11:40:17 +0100 Subject: [PATCH] iwmc3200wifi: Add wifi-wimax coexistence mode as a module parameter Wifi and wimax coexistence mode is set by wifi at boot time. There can be several modes, defined by priority tables. User space components can decide which one to select by writing to /sys/module/iwmc3200wifi/parameters/wiwi with this patch, before bringing the interface up.
