Linville" Cc: linux-wireless@vger.kernel.org, Johannes Berg Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-wireless-owner@vger.kernel.org List-ID: Splitting up previous patch as requested. Added a nl interface to set the peer bssid of a WDS interface. I also have patches to iw to add a "set peer" option which uses this interface. Is this the right place to submit patches to iw?
