It raised a question in my mind... When associating to a WPA network, at what point should the driver open the controlled port? With wext/wpa_supplicant, the driver relies on knowing that the supplicant sets the pairwise key first and group key second and can open the controlled port after the second key. Can we tie down the correct behaviour more tightly in cfg80211/nl80211? thanks Mark -- Mark Powell mailto:Mark.Powell@csr.com Group Leader, Host Drivers Tel: +44 (0)1223 692000 CSR, Business Park, Cowley Road, Cambridge, CB24 0WZ, UK To access the latest news from CSR copy this link into a web browser: http://www.csr.com/email_sig.php To get further information regarding CSR, please visit our Investor Relations page at http://ir.csr.com/csr/about/overview
