From 04a6445f6f5e439ef775bd18cf3f485f84bbfb1b Mon Sep 17 00:00:00 2001 From: Jussi Kivilinna Date: Fri, 28 Aug 2009 13:28:35 +0300 Subject: [PATCH] rndis_wlan: use cfg80211_wext_handler Now that cfg80211 functions are added and wext converted to use wext-compat functions, remove wext structures and disabled code.
