From 43b19952de54b0fccfcdc5968891ebe550367fe8 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 7 Oct 2010 13:10:30 +0200 Subject: [PATCH] nl80211: use new genl helpers for WDS Bill Jordan's patch to allow setting the WDS peer crossed with my patch removing all the boilerplate code in nl80211, and consequently he didn't make use of it yet. Fix that. Signed-off-by: Johannes Berg Signed-off-by: John W.
