    [VLAN]: Fix early vlan adding leads to not functional device · f4637b55

    OK, I can see what's happening here. eth0 doesn't detect link-up until
    after a few seconds, so when the vlan interface is opened immediately
    after eth0 has been opened, it inherits the link-down state. Subsequently
    the vlan interface is never properly activated and are thus unable to
    transmit any packets.
    
    dev->state bits are not supposed to be manipulated directly. Something
    similar is probably needed for the netif_device_present() bit, although
    I don't know how this is meant to work for a virtual device.
