From ab644b0b51bf3170b398c087b7a34be6d3c7b7ba Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Mon, 21 Aug 2006 11:37:13 +0800 Subject: [PATCH] ipw2200: ipw_wx_set_essid fix This patch cleanups the ipw_wx_set_essid code and forces a reassociation when setting the essid to "any". I have tested this patch with iwconfig. It makes ipw2200 compliant with all the cases mentioned in the iwconfig man page. The commands iwconfig iface essid any iwconfig iface essid -- any iwconfig iface essid off iwconfig iface essid on all seemed to work correctly. None of this worked before the patch. Note, this patch treats iwconfig iface essid iwconfig iface essid "" The same. It produces an error message: essid: Unknown host. Since an essid of "" is not mentioned in the iwconfig man page.
