[PATCH] softmac: Fix inability to associate with WEP networks
Commit 4cf92a3c was submitted as a fix for bug #8686 at bugzilla.kernel.org (http://bugzilla.kernel.org/show_bug.cgi?id=8686). Unfortunately, the fix led to a new bug, reported by Yoshifuji Hideaki, that prevented association for WEP encrypted networks that use ifconfig to control the device. This patch effectively reverts the earlier commit and does a proper fix for bug #8686. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
