From cbe8fa9c5e88fd5f554ebc519af3b0ed17dde0dd Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sat, 9 May 2009 20:09:03 +0200 Subject: [PATCH] cfg80211: put wext data into substructure To make it more apparent in the code what is for wext only (and needs to be #ifdef'ed) put all the info for wext into a substruct in each wireless_dev.
