cms: regenerate NetworkManager connections
    
    After changing the kernel command line, the cmsifup script calls ifup
    to activate the interface. However, ifup is only available in the
    network-legacy module; when using the network-manager module, we
    should regenerate connections according to the command line; then
    later NM will be run and will activate the device.
