From 9829e1b510214956bc9d5e278be49d781e1a6fbf Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Fri, 16 Oct 2009 13:18:57 +0800 Subject: iwmc3200wifi: Try shared auth when open WEP fails When we fail to associate with an open WEP AP, we fall back to shared auth. This allows us to support joining a shared auth WEP AP with iwconfig. Signed-off-by: Samuel Ortiz Signed-off-by: Zhu Yi Signed-off-by: John W.
