Patch from Tom Parker * Add autoip/Link Local Addressing support when we fail to get a DHCP address * Longer pause after setting ESSID on cards that support a larger number of channels to give the card time to find the right channel * Add system hook to restart mDNSResponder (or whatever the local implementation of Multicast DNS is) when we activate interfaces git-svn-id: http://svn-archive.gnome.org/svn/NetworkManager/trunk@341 4912f4e0-d625-0410-9fb7-b9a5a253dbdc
