From 2c706002fc147decdba2658ea48e4436faca3af2 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 30 Oct 2008 22:09:54 +0100 Subject: [PATCH] don't use net/ieee80211.h Convert all the drivers using net/ieee80211.h to use linux/ieee80211.h. Contains a bugfix in libertas where the SSID parsing could overrun the buffer when the AP sends invalid information.
