Title:
  Network Manager loose wired link when using 8021q (vlan manually)

Status in network-manager package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: network-manager

  Intrepid handled corretly, but after fresh install to Karmic the NM
  0.8 stops managing wired ethernet when using manually created vlan
  interfaces.

  1. NM0.8 managing eth0 corretly (dhcp - 10.0.0.26/24)
  2. modprobe 8021q still ok
  3. edit /etc/network/intefaces:
      iface eth0.200 inet static
          address 10.26.0.26
          netmask 255.255.0.0
  4. ifup eth0.200 to brings vlan200 and set static ip for it
  5. NM0.8 lost wired connection and device unmanaged
  6. ifdown eth0.200 -> NM0.8 works on eth0 again.

  If I create vlan by hand (which is not in the interfaces file) it works fine.
     3. edit /etc/network/intefaces remove all line (eth0.200) except:
  	auto lo
  	iface lo inet loopback
     4. service network-manager restart (for reload the config file)
     5. vconfig add eth0 200
        ifconfig eth0.200 inet 10.26.0.26/16
     6. NM 0.8 handle eth0 corretly and the manually created eth0.200 works fine...
