Subject: [PATCH] Fixed BSSID step 4: Don't merge if BSSID is set manually
Date: Tue, 06 Jan 2009 03:08:10 +0100 [thread overview]
Message-ID: <20090106020810.302730@gmx.net> (raw)

If you set a fixed BSSID manually, you never want that the driver change it back, or your ad-hoc mesh network will break into peaces. So don't do it.
