Title:
  "ip link delete" returns "RTNETLINK answers: Operation not supported"
  - OpenStack Juno is completely broken in Trusty + Linux 3.19.

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Guys,

   I just upgraded my Trusty with "linux-generic-lts-vivid" that is
  available in proposed repository.

   OpenStack is completely broken now. I'm using it with VXLAN +
  OpenvSwitch. All Tenants are offline.

   I'm seeing the following error at Network Node (Neutron L3 Router):

  It also doesn't work manually:

  root@network-1:~# ip link delete tap3da8f4fe-55
  RTNETLINK answers: Operation not supported

  dmesg shows this:
