From a4f7b2e823d05e500ccb2c35a68e454e8e672224 Mon Sep 17 00:00:00 2001 From: David Kilroy Date: Mon, 19 Sep 2011 21:08:15 +0100 Subject: [PATCH] staging: wlags49_h2: Support standard WEXT events ... instead of using IWEVCUSTOM. Use the defined events for michael mic failure, association request info and association response info.
